Manufactured from 1851 to 1860, this example is the earliest type with the manually revolved 6-shot cylinder and a button release mounted inside the trigger guard. Total production on this type was about 900. Marked "MASS. ARMS CO./CHICOPEE FALLS" on the top strap and "MAYNARD'S PATENT/SEP. 22. 1845" on the primer cover. Matching serial number on frame and back of both grips. The primer door and left side of the frame feature a scroll engraving with a floral type pattern engraving on the back strap and hammer and floral etched pattern on the cylinder. Casehardened hinged top strap and hammer, with the remaining surfaces blue. Brass pin front sight, notch rear sight on the top strap and smooth walnut grips. The partitioned walnut case is lined in green velvet. The following accessories are included: a Massachusetts Arms Co. double face powder flask, an extra floral etched pattern cylinder, container of Massachusetts Arms Co. primers (with primers), double cavity brass bullet mold, key and brass ramrod.

Fine. The revolver has a smooth gray patina with the barrel retaining 60% original blue finish. The grips are very fine with a series of minor marks on the bottom of the right grip panel. The engraving and etching are crisp. Mechanically fine. The modern relined and refinished case is good. The accessories are all fine and original.
