yessir, best to just "put the word out" as well as the numbers, never know folks will happen to look, see just what THEY may have, and it goes on and on, that why why the older timers ( like Bob C ) mentioned above always said they had to look ,see, pick up and pay attention to, every old model they ever see at a show. I know for a fact our friend Bill Hall was at an OGCA meeting many years ago , down in Wilmington,Oh and he brought over to me an old RST-4, that was the same number as another misnumbered "D" target model, my wife had, and said he thought it was the same number and it was and it was "cheap" besides,so NEVER say never...oh yes and our late friend Don W. found an old red eagle RST-4 over at Jacquas here in western OHio and it was the SAME serial number as a red eagle my wife had in her collection, BOTH serial number #2720.........hhhmmm
so do keep on looking, and asking...........
