Collectors use two classifications for the Polish VIS wz 35 pistols made between 1936 and 1945.
Polish Radom - these have the Polish eagle and year of manufacture stamped on the left of the slide and are the most valuable.
German Radom - made after Sept. 1939 under German occupation. There is no eagle or year of manufacture. The GErman Ordnance designation is on the slide - P-35, I think.
