Approximately 1,500 to 2,000 of these automatic revolving cylinder type revolvers were manufactured from 1857 to 1861 with very few engraved. The top strap is marked "MASS. ARMS CO./CHICOPEE FALLS". The primer door is marked "MAYNARD'S PATENT/SEP. 22. 1845" in a circle surrounded by scroll engraving, "NOV. 26. 1850" on the front of the barrel latch and "PATENT/JAN. 2, 1855" on the back strap. The inside of the top strap is marked "408" and the left side of the frame under the primer door and grip, and the inside of the primer door are marked "236". Broad leaf floral scroll engraved frame and primer door, with a zig-zag border on the back strap, and floral etched cylinder. Blue finish with casehardened top strap and hammer, and fitted with smooth walnut grips.

Excellent. The revolver retains 95% bright original high polish blue finish with scattered areas of smooth brown patina. 90% of the original case colors remain on the top strap and hammer. The grips are very fine with most of the original varnish remaining and showing some minor lower edge wear, dings and dents. The markings, engraving and etching are crisp and clear. The action is excellent.
