Sorry I can't show you how they work and I didn't know that pin fire cartridges were reloadable. The two photos are following. This is also a good explanation of the Pin fire cartridge on the web site below.
3 A 12B G & J.W. Hawksley pinfire redecapper
3 B is a pinfire redecapper and cartridge trimming tool. At the end of the handle is a knurled wheel on a grub screw which is used to grip the old pin to remove from the cartridge. The tool also incorporates a cartridge trimmer blade which emerges when the knurled ring on the body of the tool is turned.
L'Arbalete LaSauterelle type A D'Imphy grenade thrower, saw one once in a museum and it was strange enough that I remember it. (Don't trust my spelling, French and I do not get along well.)
The device was called L’Arbalete la Sauterelle Type A D’Imphy, and it quite literally was a crossbow, using the tension of two bent steel rods to provide the energy storage that sinew provided back when the Romans were building this sort of thing. A metal cup held a spherical Type 14 grenade (weight roughly 1kg/2.2lb), and a pair of hand cranks on a rack and pinion mechanism were used to cock it. The device was designed by a French artillery officer by the name of Elie André Broca.
There is a lot more great reading at Forgotten weapons
This one really surprised me. I thought I knew a great amount of information on the designer of this rifle but I didn't know about this gun. Well I wont make that mistake again
Garand SR-M1 Carbine I knew that wouldn't last long with the X perts around here
While looking I found out about his carbine. There isn't very much on line that I can find about it. I tried looking for the original report on the testing of the gun VS others but came up with a wall. I would find it interesting to read the government report if any one knows how or where to look? https://www.nps.gov/spar/learn/historyculture/m1-variations.htm http://www.forgottenweapons.com/light-rifle-program/garand-carbine/
U.S. Rifle SR M1 Garand .30 caliber
This “Short Rifle” was designed by John Garand and competed against the Winchester entry which was adopted as the M1 Carbine in 1941.
Ah ha! I knew it had something to do with the Tommy gun. I guessed it by looking at front and rear sights of the gun. It was the signature Thompson style.
