About three years ago, I acquired an Edison A-200 Disc Phonograph, and although the metal finish on the machine as a whole was the conventional gold-plated surface, the crank (which obviously must have come from another machine) has the oxidized bronze finish, and a richly colored original walnut finish on the wood handle portion. It seems to fit the machine quite well in terms of approximately proper distance from the cabinet to the elbow, and is clearly an Edison crank. Could this have originally been on an Amberola A-1 or similar machine with the special finish? Were any Diamond Disc machines offered with this finish on the metal parts? Andy Baron
