In 1938, the Wehrmacht looked to replace its legendary Pistole Parabellum 1908, better known as the Luger. It chose as its replacement the Walther-designed Pistole 38, however Walther wasn't the only manufacturer of these handguns.
Three manufacturers produced collectively over one million P.38s during the war. Walther was the earliest to begin production in June 1939, followed in 1942 by both Mauser and the lesser-known Spreewerk.
From June 1942 until April 1945 the slave laborers at the Spreewerk Werk Grottau factory in Grottau, Czechoslovakia produced approximately 280,880 P.38s. As the war progressed, the steel slides on these examples often exhibited a rougher finish than those produced by Walther and Mauser.
At slightly under 300,000 P.38s, Spreewerk produced the least of the three manufacturers. Also differentiating itself from Walther and Mauser, Spreewerk examples were the only complete wartime P.38s produced outside of Germany. With that said, some individual components were also manufactured in other countries - most notably slides produced by Fabrique Nationale in Herstal, Belgium.
The only wartime P.38s that clearly display the names of their manufacturers are those produced during the first few months of the war by Walther. Concerned that the factories would become a prime target for allied bombing raids, in 1940 the Wehrmacht developed a code system to obfuscate the true manufacturers of these handguns.
Most Walthers were marked 'ac'. The majority of Mausers were marked "byf", however in 1945, shortly before French occupation of their factory, Mauser changed its marking to "svw", just in time to produce roughly 15,000 more P.38s. Lastly, Spreewerk examples were marked "cyq". Some Spreewerk P.38s appear to be marked "cvq", however that is likely due to a damaged die stamp, where the leg of the "y" was missing.
Now that you know a little more about this somewhat uncommon P.38 manufacturer, view this chart in order to determine the production date of your example.
Cyq 7660 t still all matching 90 % bluing AUG 1944
my P38 is cyq # 743 c.
I have a P38 with marking: Left side slide-P38 on the front of the slide, cyq in the middle of the slide and 6761 with a U lower and not next to the serial number fairly close to the safety. Right side slide- there a 5 different proofs and the only one I can make out is the eagle with the nazi symbol underneath. On the left side of the frame under the slide release is 6761, next to it is a U and next to the U is the something with three lines in it over the numbers 88. On the front of the gun under the barrel is 6761 with the letter U directly underneath. The slide…
I have a “cyq” with serial number 425-k….I presume it was manufactured in December, 1943?
I have a cvq-marked (not cyq) P.38 ser. # 656 with no prefix or suffix, no import marks, faint E/88 stamps, rough machining marks, non matching # trigger guard (46), waffenampts on L side frame and L side triggerguard defaced. Capital E next to defaced waffenampt on L side triggerguard. Thoughts?
