Colt Single Action Army 2nd Gen Cylinder +Barrel + Bushing NOS W/Box

This is a box with parts that came from Colt Firearms I believe in the 1950's. Parts were not used. The box bottom has a small piece of the shipping label from Colt. There is a 45 cylinder with nickel finish. It has the Horse logo stamped on one end. Nice original Colt cylinder with excellent finish. There is a barrel that is stamped on one side: COLT SINGLE ACTION ARMY 45. The other side is stamped: COLT'S PT. FA. MFG. CO. HARTFORD CT. U.S.A. The barrel is in excellent clean condition with a shiny clean bore. The barrel is end to end 4 3/4 inches long and is 4 inches without the threads. There is also a cylinder bushing. I believe all pieces to be new old stock as ordered back in the 1950's and unused.
