this gorgeous example is a Frontier Six Shooter and is so marked on the left barrel (is can be clearly seen but just too difficult to photograph. sorry) it is in 44-40 Caliber with 7 1/2 inch barrel and the serial number tells us that it was made in 1881 when gun slingers still ruled the west. The ivory grip are perfect with no cracks or breaks . You won't find a better example.
