This is an original sales flyer from maybe the 1962-63 time period. I have soime letters from Col Driscoll (sp) but they are cuirrently packed. This flyer was in a different file. This is a tri fold flyer that I got at the time. Had approval from Col Driscoll to purchase one but someone higher up killed that. Col Driscoll was in charge of the program for this gun at H & R. Not sure how many were actually made, never have seen any of the special muzzle breaks available that were not copies. . .
