Beretta M35 pistol in 7.65 Browning Mod.35/1945, is the so-called "war finish" version, produced between January and April 1945. Still wartime. The oval stamp is the 4th UT test, which on these weapons is positioned "prone" compared to those of 1944 (in which it is correctly vertical).
Only 15,000 pieces were produced, out of 600,000 to 615,000.
