Underhammer Target Pistol percussion model
Among the various guns manufacturers of underhammer, Michael Carleton of Haverhill, New Hampshire, made the model that prevailed over other models thanks to the liner movement of the hammer having a parallel motion to the barrel axis. The nipple is horizontally screwed to the drum placed in the under part of the frame and the main hammer spring looks like a trigger guard.
The sliding moving parts are carefully designed to reduce their friction: the result is a very moderate crisp pull, even without a set trigger.
This very well balanced gun is made with rust brown finish colour barrel, completed with a saw handle stock, providing a firm and natural grip.
