Jon-
Didn't military contract M1911A1 production stop after 1945? I'd say except for small parts, the pistol must be '45 or earlier
Here's my Spreewerk P.38. 1944 production; a well-made example for late war
In the last days of the European war, as the 3rd Reich collapsed, the Kreigsmarine found itself on land, defending Doenitz and his attempts to end the war. Erich Topp, Freggatenkapitan and U-boat ace, was ashore receiving his last orders, to take the U-2513 to Norway. In his haste to leave, Topp left behind most of his personal effects, a small bundle anyway because U-boats were cramped and tiny. The bundle was hidden by fleet staff but was found when the Russians took Berlin. Like many captured German small arms, Topp's P.38 was turned in and stored for post-war Red Army use and training until Soviet production could again keep up with the needs of the Red Army. In the late 1990s, the crate the pistol was in and many other crates like it were offered up for sale as entire lots of warehouse inventory were sold to Western entrepreneurs. being the meticulous records-keepers they were, the Waffenamt dutifully took down the serial number of Topp's pistol when it was issued to him in October of 1944. Southern Ohio Guns was one of the purchasers of the various Lots of warehoused ex-Soviet material; I purchased Topp's pistol from them...
...of course that is complete Bull. Buy the pistol, not the story. Who knows who was issued my P.38 in WWII. All I know is it was made in Czechoslovakia in 1944, captured by the Russians, refinished in a tough, un-lovely dip blue, and through some means imported to the US a few years ago, and I bought it. All numbers matching, 'jvd' marked mag, fair bore, actually a good shooter
The map is a reproduction of a WWII Kreigsmarine map of a similar type that would be on a U-Boat. Of course, the paper isn't water-soluable
