I have an F.B Radom VIS Mod.35 that I would like to know the value of. The pistol is marked as follows: On the left side of the slide “F.B.RADOM VIS MOD.35.Pat.Nr.15567.(an eagle symbol – looks like a real bird) and (another symbol that looks like a scale). The second line on the slide shows the eagle (different from the one on the first line) above the letters WaA77 followed by “P.35(p)”. The eagle and WaA77 also appears on the receiver.There is also what looks like two small “V”s and something else on the trigger guard. On the right side of the pistol the serial number”D0259” is stamped on the receiver. The pistol has a decocker, take down latch, grip safety, shoulder stock slot, and lanyard loop. It also has black plastic grips with FB on one side and VIS on the other. I believe this makes this one of the first Nazi production guns referred to as Grade 1 German VIS. Thanks for any help.
