Bob,
Brammer was written up in Muzzle Blasts, with a cover picture , I think in 1947. He was well known and known as Uncle Geo. He was one of the ML builders who successfully transitioned into the cartridge rifles. A friend of mine's father knew Brammer and when they broke up his shop, got the rifleing machine. The cutters came from another friend and the rifle was in Indiana. If you can make it we, Ohio Longrifle Collectors, are holding our 36th annual exhibit and annual meeting in Marietta on April 13th-14th at the Lafayette Hotel. Would look forward to seeing you.
Mark
