Bonjour, oui, ce M signifie Modifié, par la France au début des années 50. "M" pour "Modifié".
At the beginning of the 1950s, the APX received the order to modify the optics of 2675 “ZF 41” scopes which would then have to be sent to the national arms factory in Saint-Etienne to be mounted on MAS automatic rifles in caliber. 5.5 mm.
These scopes come from the captures made by the Allied troops in Germany in 1945. We then discover that the national arms factory in Châtellerault had an impressive stock of them in its workshops ...
The inventory produced by the MAC in 1951 shows 18,902 ZF 41 and ZF 41 / I scopes.
The project was abandoned because the modification made was not reproducible on all models of zf41 types 1, 2 and 3. And this stock of glasses and spare parts was sold to the civilian population at the end of the 1950s. Part of the stock of transport boxes associated with this lot of glasses was destroyed.
