Also known as the John Brown Model, only around 1,000 of the Maynard primed belt revolvers were manufactured from 1851 to 1857. The 31 caliber, 6 shot manual rotating cylinder has floral and military etching, and traditional acanthus scrollwork is engraved on the lock, frame, and hammer. The top strap is marked "MASS. ARMS CO./CHICOPEE FALLS," and "MAYNARD'S PATENT SEP. 22, 1845" with eagle/shield motif is marked on the door of the Maynard primer and accented by border engraving. It has the assembly number "157" on the barrel barb and cylinder pin and the serial number, "554," on the recoil shield, lock, back of the frame, back strap, and grip. The front sight is a tall rounded blade, and the rear sight is a small fixed notch at the rear of the top strap.
