Tom, I don,t have personal knowledge of a qualified gunsmith in the Memphis area but once you locate barrels post again and revdocdrew will probably be able to help you out. Try a pawn shop search, check antique shops(the cluttered kind) and local gun shops. The key is to ask about parts and part guns at the gun shops. They will not be on display. Also lonely barrels seem to migrate to dusty corners and hide behind mops and amongst clutter. Look carefully. Good luck, Peter
