Cal 45. 5-1/2" bbl. Excellent bore. Original sights. About 90% bbl blue remaining. Cylinder blue is pretty much in tact with a few drag lines. Case hardened receiver has about 75-80% bright case colors. Gun is also fitted with factory checkered grips with Colt Medallion. Engraved on the backstrap is "Richard Garland". Gun was alleged to belong to an actor named Richard Garland who was in a number of old western shows such as Virginian, Rifleman, Zoro, Daniel Boone,The Rough Riders and several others as well as a long run on "Lassie". A very fine gun that should make a good shooter.
