Covered by patent number 182, issued to Daniel Leavitt on 29 April, 1837, the beveled cylinder was designed to direct the flash from the cylinder gap away from the other chambers, which was thought to reduce the chances of a potentially destructive or fatal chain fire. A very similar arrangement would be seen on weapons produced by Massachusetts Arms Co. The barrel support, which attaches the barrel to the action, slips over the cylinder pin and is fastened by a screw to the top of the frame, and a pin through the cylinder pin. It has grooves on each side to deflect the bullets in case of multiple discharge. This piece is almost identical to the pistols and rifles made by James Warner and the Springfield Arms Co. The loading lever is also nearly identical in shape and function to the Springfield. German silver blade front and deep notch rear sights, with an engraved commercial lock plate, double set triggers and thin oak stock, suggesting rural New England manufacture, but there are no markings to verify this. The cylinder is released for turning by a button in front of the trigger guard.
