Colt Thuer – This conversion is acknowledged as Colt’s first metallic cartridge revolver, produced from 1869-72, long before the Single Action Army appeared. One unique feature was the ability to shift back to using a percussion cylinder, which probably came in handy if a user were to run out of metallic cartridges, but still could obtain percussion caps, powder and ball. This M1860 “Army” revolver with the Thuer conversion cylinder in place also bears some well-aged ivory grip panels.
