Again, Dutch is correct. Lacquered-steel case 765 mm Browning ammunition was made at Fabrique Nationale d’Armes de Guerre, Herstal, under the German occupation and the stewardship of DWM who owned the factory, I believe, through stock control, even before the occupation. The 7.65s made at FN have the DWM headstamp and were made in 1942, 1943 and 1944.
Gustave Benschow & Cie. (GECO) also made lacquered steel case 7.65 mm Browning, as did Ateliers de Construction de Tarbes, in France, during the German Occupation, using the code “pyj” on the headstamp. Société Française des Munitions did as well, but the only dates I recall seeing in their production are Post-WWII, 1946 and 1947. I don’t collect dates, so there could be others. Sellier & Bellot of Czechoslovakia made it also with the SBP headstamp, but I forget off hand if that was wartime production, or post-war.
While I have no regard for the caliber as a pistol cartridge for self-defense, or any other use for that matter, the 7.65 mm Browning is a nice cartridge for collections. Not quite as varied as, say, the 9 mm Para, but plenty of interesting stuff there to collect. I like the three “pocket calibers” (6.35 mm/.25 A.C.P., 7.65 mm Browning/.32 A.C.P. and 9 mm Kurz (Court, Skurt, Corto, short, Kisa, etc.) very much and have since I started collecting.
Dutch - since you are really a 7.9 collector, you should send me that nice 7.65 Browning DWM Herstal box so it will be in the right collection! :-)
