546 IWI Jericho 941
https://en.wikipedia.org/wiki/IWI_Jericho_941
The Jericho 941 is a double-action/single-action semi-automatic pistol developed by Israel Military Industries (now: Israel Weapon Industries) that was launched in 1990.
It was first imported into the US in 1990 by K.B.I., Inc. of Harrisburg, Pennsylvania. It was later imported by O.F. Mossberg & Sons and named the Uzi Eagle and by Magnum Research, Inc. as the Baby Eagle until the end of 2008. Some pistols from Magnum Research are marked Desert Eagle Pistol. Despite these names being used in the US market, the Jericho 941 is not related to the IMI Desert Eagle other than its manufacture and design by IMI, and bears only a slight cosmetic resemblance to the larger pistol. From January 2009 until they ceased business in January 2010, K.B.I., Inc. (which also imported Charles Daly firearms) imported the handgun as the Jericho. Magnum Research, now a division of Kahr Arms, announced a renewed importation of the Jericho.
In December 2014, IWI US, Inc. announced they would begin importing both the steel and polymer versions of the Jericho 941 in early 2015.[1]
Design and features[edit]
The original Jericho 941 was modeled on the well-respected CZ-75 pistol designed and produced by Česká zbrojovka (CZ) of the Czech Republic and built using parts supplied by the Italian arms house Tanfoglio, which had been making their own CZ-75 clones. Using a well-tested design allowed IMI to avoid the teething problems most new pistol designs experience, and subcontracting much of the basic fabrication work to Tanfoglio allowed IMI to quickly and economically put into production a pistol that would have enough Israeli content to satisfy government contract requirements.[2]
While the R-versions of Jericho 941 feature a combined safety/decocker (the decocking lever also acts as a safety and remains on "safe" when actuated), the decocker version of the CZ-75 (CZ-75BD) features a simple decocker (the pistol is always ready to fire in double-action mode when decocked). The barrel of the CZ-75 is traditionally rifled, while the Jericho 941 features a polygonal barrel, furthermore the Jericho 941 is substantially heavier. These differences translate into substantial differences in the condition in which the gun is carried. Magazines for the CZ-75 and Tanfoglio T95 will function in the Jericho 941.
One innovation by IMI was a new, much "hotter" cartridge, the .41 Action Express (see below) to go along with the Jericho 941. The difference between 9mm and .41 AE is the same as .44 Magnum and .50 AE. The AE bullets have rebated rims which are the same diameter as the less powerful rounds, but the case is wider, providing more power. This allows these pairs of calibers to be used in the same firearm with only a change of barrel, recoil spring and magazine.[2]
The .41 AE was less commercially successful than the 10 mm, and was soon discontinued.[3] Experience with heavily loaded rounds gave IMI a considerable lead, however, in chambering for the soon-to-be successful .40 S&W and also allowed the Jericho to "up-chamber" to the very popular .45 ACP.[2] The Jericho 941 design has been modified to include accessory rails on the frame for mounting lasers or flashlights, a feature found on many current-generation semi-automatic handguns.
The introduction of the Jericho 941 also introduced a new caliber to the market, the .41 Action Express (or .41 AE), which was developed in 1986.[2] The .41 AE was a unique rebated rim cartridge designed to use .410-inch (10.25 mm) bullets and duplicate a reduced power police loading of the .41 Magnum.[3] The Jericho originally shipped with two barrels, one for 9×19mm Parabellum and the other for .41 AE. Since the .41 AE was designed with a rebated rim the same dimensions as that of the 9 mm, the extractor and ejector worked equally well for either cartridge.[2]
Ballistically, the .40 S&W was similar to moderate .41 AE loads (the reloading manuals that list the .41 AE generally say to use .40 S&W data), although commercial loadings of .41 AE were somewhat more powerful than the .40 S&W. With the stronger backing of major American firearms and ammunition manufacturers, the .40 S&W quickly pushed the .41 AE out of the market. The Jericho 941 was only on the market for one year before the dual 9 mm/.41 AE chambering was dropped, and the pistol was sold as either 9 mm or .40 S&W. Some shooters like the Baby Eagle in .40 S&W for its extra reserve of strength, since the Baby Eagle was originally designed for a more potent cartridge (the .41 AE), which is the reverse of some makers who dropped .40 S&W barrels into pistols previously spec'd for the milder 9 mm cartridge and had subsequent barrel and cartridge case failures.
A later compact version, the Jericho 941, was chambered in .45 ACP or 9 mm. It is not clear to what extent the Jericho original 41. AE/9 mm Jericho frame and slide were "built-up" to handle the .45 ACP's much larger diameter; although the .45 ACP is a milder load running at much lower pressures than the .41 AE, the barrel opening for the .45 ACP is, of necessity, much larger. Desert Eagle does not permit the use of +P or +P+ loads per its website FAQ, although reviewers have shot and reported the ballistics on +P .45 ACP defensive loadings.
Initially Jericho pistols used barrels with polygonal rifling, which sometimes produces slightly higher velocity due to better bullet to barrel fit. IWI switched to conventional land and groove rifling from 2005 to 2007.
The Jericho 941 is issued in current service throughout the Israeli Security Forces, and Israel Weapon Industries lost a 1.2 Billion Pesos bid for the Philippine National Police's 60,000 handgun procurement on July 11, 2012.

You've never heard of the Semmerling LM?
Don't feel bad.
Not a lot of others have, either.
I got to fire one when I worked at NRA. Kicked like a freaking mule, and the grips made it a lot worse, at least for me.
Operation was funky, but once you got the hang of it you could operate it fairly quickly.

191 Semmerling LM4
One being fired and proof with what Mike Irwin said about a mule

https://en.wikipedia.org/wiki/Semmerling_LM4
The Semmerling LM4 is a five-shot, manual repeating double-action pistol designed for backup purposes.
Concept and History[edit]
The Semmerling series of pistols included the LM1, LM2, LM3, LM4 and XLM. The only version available to the public was the LM4 which was first designed and manufactured in the U.S.A. in the early 1980s and marketed at a price of US$750. The "LM" in the model numbers stands for "Lichtman Model", after the inventor of the design, Philip R. Lichtman. Lichtman applied for and received at least four United States Patent's related to the design.[1]
The goal of the LM4 was to achieve a combination of the highest practical firepower in as small and light a gun as possible, so as to be easily concealable. This was approached by selecting the service caliber of .45 ACP for its proven stopping power and opting for a manual repeating mechanism to minimize bulk and weight and ensure flawless operation in the most difficult situations. Because of this the LM4 was first offered to the U.S. Army and government agencies.[citation needed]
The Semmerling LM4 is simple, having only 33 parts (including screws).[citation needed] The original design called for every part except for the springs to be made of S-7 tool steel. Every pistol was Magnafluxed (a method of testing ferrous metals for surface and subsurface flaws) twice in their assembly.[citation needed]
Each pistol was essentially handmade to order with production averaging a little over ten pieces a month.[citation needed] Of the LM4 model, only about 600 were ever produced.[citation needed]
Although the Semmerling was intended as a back-up pistol for those most at risk of having their primary weapon taken from them, some[who?] adopted the pistol as a "hide-out" weapon.[citation needed] It is capable of a "shot-a-second" firing rate. With the magazine loaded and a round in the chamber, the Semmerling LM4 is capable of carrying five .45 ACP rounds.
During 2005, the largest collections of Semmerlings comprising examples of the LM1, LM2, LM3, LM4 and the XLM along with all prototypes, tooling, drawings, production and testing equipment, advertising materials and leather accessories were provided to The National Firearms Museum, The Cody Firearms Museum and the Smithsonian. The XLM was a military contract for an automatic version (not manually operated), making the Semmerling XLM the smallest .45 ACP automatic ever produced.
A stainless steel version, not part of the Semmerling Corporation's efforts, has been available at request from the American Derringer corporation since about 1995.[2]
Finish and accessories[edit]
The original standard color was matte black with highly polished slide frames. A complete high polish blued finish or a hard chrome plating were optional. A factory presentation model was produced with a high polished gold plated slide.

211 MAS-49
https://en.wikipedia.org/wiki/MAS-49_rifle
The MAS-49 is a French semi-automatic rifle that replaced various bolt action rifles as the French service rifle that was produced from 1949. It was designed and manufactured by the government-owned MAS arms factory.[1] The French Army formal designation of the MAS-49 is Fusil Semi-automatique de 7,5mm Modele 1949 ("semi-automatic rifle of 7.5mm model 1949"). The MAS-49 semi-automatic rifle was produced in limited quantities (20,600 units), whereas the shorter and lighter variant, the MAS-49/56, was mass manufactured (275,240 units) and issued to all branches of the French military. Overall, the MAS-49 and 49/56 rifles gained the reputation of being accurate, reliable and easy to maintain in adverse environments. All the MAS-49 and 49/56 rifles feature a rail on the left side of their receivers to accommodate a designated rifle scope. The MAS-49 and MAS-49/56 were replaced as French service rifles by the FAMAS assault rifle in 1979.
History[edit]
The MAS-49 arrived after a series of small, distinct design improvements. Today, this might be termed spiral development, where small elements are changed with successive models, rather than large significant changes. This French semi-automatic rifle evolved from the prototype MAS-38/39 and from the MAS-40 which entered limited service in March 1940, and lastly from the post-war MAS-44 and its minor variants 44A, 44B and 44C. Although 50,000 MAS-44 rifles were ordered in January 1945, only 6,200 were delivered to the Marine Nationale. The MAS-49 was formally adopted by the French Army in July 1949. As a service rifle, it replaced the diverse collection of aging bolt-action rifles (MAS-36, Lee–Enfield No4, U.S. M1917, Berthier, and K98k) that were in French service after the end of World War II. It saw significant service with French troops in the latter stages of the First Indochina War, as well as during the Algerian War and the Suez Crisis.[1]
An improved version called the MAS-49/56 was introduced in 1957 and incorporated lessons learned from service in Algeria, Indochina, and the Suez Crisis. The rifle was shortened and lightened to improve mobility for mechanized and airborne troops, and a knife bayonet was added. The MAS-49 built-in rifle grenade launcher was replaced by a combination compensator/rifle grenade launcher that fired NATO-standard 22mm rifle grenades. The rifle also incorporates an integral grenade launching sight that is attached to the front sight block and a gas cutoff that prevents gas from entering the gas tube from the gas port when firing grenade launching blank ammunition.
Attempts were made to replace the MAS-49, in the form of the MAS-54 and the FA-MAS Type 62, both 7.62×51mm NATO battle rifles, but neither were successful. The MAS-49/56 ended production in 1978 and was replaced with the 5.56×45mm NATO caliber FAMAS bullpup assault rifle. The MAS-49/56 was withdrawn from service in 1990.[1] Whereas only 20,600 MAS-49 were manufactured, the MAS-49/56 was mass-produced, attaining a total of 275,240 rifles issued between 1957 and 1978.
Technical characteristics[edit]
The direct impingement gas system was first applied in 1901 to a 6mm semi-automatic experimental rifle (the ENT B-5) designed by Rossignol for the French military (by definition, the direct impingement system lacks a gas piston).[1] Although several experimental prototypes using a tilting bolt and direct impingement had been tested by MAS since 1924, the immediate precursor to the MAS 7.5mm semi-automatic rifle series is the MAS-38/39.[2] It was successfully tested in March 1939, just before World War II, and followed in May 1940 by the nearly identical MAS 1940. Similar direct impingement designs include the Swedish AG-42 Ljungman semi-automatic rifle adopted in 1942 and the US M16 select-fire rifle adopted in 1963. In the MAS-49 system gas is vented from a port on top of the barrel and piped directly into an open cylindrical hollow located in front and on top of the bolt carrier. The system has the advantage of not depositing gas fouling on the bolt itself, a separate part located underneath the bolt carrier. All the French MAS 7.5mm semi-automatic rifles mentioned herein feature a rear-locking tilting bolt, as on the M1895 Colt–Browning machine gun, the Browning Automatic Rifle (1918), the MAS-1924 to MAS-1928 experimental semi-auto rifles, and the Russian Simonov SVT-38 (1938) and SVT-40 (1940) rifles.
The same 10-round detachable magazine fits the MAS-44, MAS-49 and MAS-49/56 rifles. The earlier MAS-40 (1940) rifle had a 5-round magazine within the receiver, as on the bolt action MAS-36 rifle. Lastly, the MAS-49 and MAS-49/56 are equipped with a rail on the left side of the receiver. It allows for the immediate installation of a "Modele 1953" APX L806 (SOM) telescopic sight by sliding it into place and then locking it in with a small pressure lever.[1] The MAS-49 and MAS49/56 are capable of consistently hitting individual man-size targets up to 400 meters with the adjustable peep sight and up to 800 meters with the APX 806L telescopic sight. The bore is counter sunk at the muzzle to protect the rifling and preserve accuracy. The barrel is freely floating.
The MAS direct impingement design reduced the number of bolt moving parts to only six: the bolt carrier, then the rear locking tilting bolt which carries the extractor, the ejector and the firing pin, and lastly the recoil spring. It takes only a few seconds to disassemble the entire bolt mechanism for cleaning. The MAS-49 had a reputation for reliability in conditions of poor maintenance, sometimes being cleaned with nothing more than rags and motor oil. The rifle could also endure harsh service environments (MAS rifles saw service in Algeria, Djibouti, Indochina, and French Guiana).
MAS-49 rifles produced for Syria differed slightly from the French service model by having a spike bayonet identical to that of the MAS-36.[1]
Many MAS-49/56 rifles imported as surplus into the USA were rechambered locally by Century Arms International to fire the 7.62mm NATO round. However several user reports have noted that these particular conversions were often unsatisfactory (resulting in numerous action stoppages and misfires) due to imperfect workmanship. Furthermore, the shortening of the barrel to allow rechambering brings the gas vent closer to the chamber hence creating a higher stress on the bolt carrier. In addition to these Century Arms conversions, approximately 250 MAS-49/56 rifles were converted in France to 7.62mm NATO for use by the French National Police. These rifles are not known to have the reliability issues that plague the later Century Arms conversions.
Commercial 7.5×54mm "French" ammunition made in countries other than France for current distribution have been known to produce burst fire (2 or 3 rounds at a time) because of more sensitive primers.[3] The original heavy steel firing pins on the MAS-49 and 49/56 can be replaced by commercial titanium firing pins which are much lighter and generally cure the problem of burst fire on these weapons. It is also possible to prevent these slamfires by shortening the firing pin by approximately 0.5 mm, or by modifying the bolt to accommodate a firing pin return spring.

The MAS direct impingement design reduced the number of bolt moving parts to only six: the bolt carrier, then the rear locking tilting bolt which carries the extractor, the ejector and the firing pin, and lastly the recoil spring. It takes only a few seconds to disassemble the entire bolt mechanism for cleaning. The MAS-49 had a reputation for reliability in conditions of poor maintenance, sometimes being cleaned with nothing more than rags and motor oil. The rifle could also endure harsh service environments (MAS rifles saw service in Algeria, Djibouti, Indochina, and French Guiana).
MAS-49 rifles produced for Syria differed slightly from the French service model by having a spike bayonet identical to that of the MAS-36.[1]
Many MAS-49/56 rifles imported as surplus into the USA were rechambered locally by Century Arms International to fire the 7.62mm NATO round. However several user reports have noted that these particular conversions were often unsatisfactory (resulting in numerous action stoppages and misfires) due to imperfect workmanship. Furthermore, the shortening of the barrel to allow rechambering brings the gas vent closer to the chamber hence creating a higher stress on the bolt carrier. In addition to these Century Arms conversions, approximately 250 MAS-49/56 rifles were converted in France to 7.62mm NATO for use by the French National Police. These rifles are not known to have the reliability issues that plague the later Century Arms conversions.
Commercial 7.5×54mm "French" ammunition made in countries other than France for current distribution have been known to produce burst fire (2 or 3 rounds at a time) because of more sensitive primers.[3] The original heavy steel firing pins on the MAS-49 and 49/56 can be replaced by commercial titanium firing pins which are much lighter and generally cure the problem of burst fire on these weapons. It is also possible to prevent these slamfires by shortening the firing pin by approximately 0.5 mm, or by modifying the bolt to accommodate a firing pin return spring.

"Russian DP aircrew machine gun"
DA, not DP.
DA stood for Degtyaryova Aviatsionny... or Degtyaryov Aviation machine gun.
Not particularly successful, and replaced by the ShKAS, which used standard belt feed and had an incredible firing rate of nearly 2,000 rpm (3,000 rpm in a post war version).

Scorch You are partial right in that it was designed from the DP but for the gun shown
Mike is correct in that its a DA for the aircraft mounting see below.

The Degtyaryov machine gun (Russian: Пулемёт Дегтярёвa Пехотный Pulemyot Degtyaryova Pekhotny "Degtyaryov's infantry machine gun") or DP is a light machine gun firing the 7.62×54mmR cartridge that was used primarily by the Soviet Union starting in 1928. The DP machine gun was supplemented in the 1950s by the more modern RPD machine gun and entirely replaced in Soviet service by the general purpose PK machine gun in the 1960s.
Design[edit]
The DP-27 was an improvement of the earlier DP-26, both designed by Vasily Degtyaryov. The DP-27 was relatively cheap and easy to manufacture – early models had fewer than 80 parts. The DP was especially able to withstand dirt in a reliable fashion. In tests it was buried in sand and mud and was still capable of firing more than 500 rounds. One of the DP's main drawbacks though was its bipod; it could not withstand much abuse and broke easily.[1] Furthermore, the recoil spring was located under the barrel, around the gas piston; this was one of the design problems of the DP, since the spring tended to lose its temper due to overheating.[2] Also, the only magazine option, a pan with 47 rounds that fed in from the top, was relatively small and continuous fire for long periods could not be relied on as much as contemporary belt-fed weapons. The ammunition was troublesome for automatic fire. Degtyarov had to use a flat pan magazine, which could feed those cartridges reliably, but was too heavy itself, uncomfortable to carry and prone to damage.[2] Due to the design of the magazine, reloading an empty magazine with cartridges took a very long time. A redeeming factor was that the DP's lower cyclic rate of fire did reduce the risk of barrel overheating.
History[edit]
Despite its numerous problems, the DP had a reputation as a relatively effective light support weapon. It was nicknamed the "Record player" (proigryvatel') by Red Army troops because the disc-shaped pan magazine resembled a gramophone record and its top cover revolved while the weapon was fired. Many were captured by the Finnish army in the Winter War and the Continuation War and partially replaced the Lahti-Saloranta M/26. The DP received the nickname Emma in Finnish service after a popular waltz, again due to the magazine's resemblance to a record player. In the summer of 1944, the Finnish army had about 3400 Finnish-made Lahti-Salorantas and 9000 captured Soviet-made Degtyarevs on the front.
The Chinese Nationalists received 5,600 DPs from the USSR and used them in the Second Sino-Japanese War and the Chinese Civil War. The Chinese Communists used the DP in the Korean War and copied the DPM as the Type 53.
A number of the RP-46 variant of the DP have been spotted in present-day Somalia, in use with militant forces, and also among rebel forces in the 2011 Libyan uprising to overthrow Muammar Gaddafi.[3]
DP-28's have also been recovered from Taliban fighters in Helmand Province, Afghanistan as recently as 2014.
DPs or DPMs have been spotted in 2014 in the Northern Mali conflict.[4]
DA, for mounting in aircraft (Дегтярёва авиационный, Degtyaryova Aviatsionny; ДА). Also used in tandem mounts known as DA-2. Employed in the early versions of the Tupolev TB-3 bomber and in the Polikarpov R-5 and Polikarpov Po-2 fighters. The DA weighted 7.1 kg empty and 11.5 kg with standard ammunition load. Its rate of fire was 600 rounds per minute. It was built between 1928 and March 1930 with 1,200 units delivered.[5] It was soon superseded by the ShKAS, which had a much higher rate of fire.

That is an interesting revolver and yet another example of a gun used in the Civil War that I'd never heard of.

One of these days I am going to go through all of these and count up how many you have gotten right Scorch, I am impressed with your knowledge.
I couldn't find much information on the gun but Forgotten weapons has a nice video,
Forgotten weapons is in my opinion THE best video source on guns and the history.
