I picked this up at a shop in Cheyenne and am trying to find out some history on it. The one barreled action is marked John Dickson & Son Edinburgh and is chambered in 9mm Mauser. The other is marked John Maples Rosenberg Texas and is chambered in 7x57. Both share one bolt. A letter included shows it belonged to Mr. Maples in 1988. It also has a letter describing the take down to a gentleman named Buck. I know only of Buck Hamlin, but that is just a wild guess. Does anyone reconize the name or the set of guns? Thank you Paul
