This pistol may have been one I acquired in 1975/76. (the ser# 0231 kind of rings a bell). There was a advert in Shotgun News from a guy named Will Hoetzel. He was selling his extensive P35 collection, which either did have (or was close to having) one German made P35 (p) from each letter-bloc/both series plus others. I acquired a 46000 range Polish Eagle, Norwegian "dip-finished "P35(p) / WaA77" accepted Polish Eagle, a NLB KM accepted P35(p), B-range/1st series P35(p), the J-bloc, 2nd series Steyr T3 and K-bloc "bnz" with no slide serrations. If memory serves, think I paid $3K/delivered for the lot. There was another serial number in the slide tunnel which had been lined-out behind the matching J-bloc one on the example I had. Though selling all 13 of my Radoms by 1979 to put a $5K down payment on my first home, I later got back the Polish Eagle from fellow P35 collector Al Hoffmeyer... as about ten years later he had purchased most of my former pistols and more from the collector to whom I sold mine to. I always figured something dire must have happened to the majority of 2nd series, J-bloc P35(p)s and the theory they were destroyed either at a railway yard on en-route would be quite plausible at that time.
