Just under 13,000 of these palm pistols were manufactured by Chicago Firearms Co. in the 1890s, with only 1,000 in the 3700-5400 serial number range estimated to have blue finish like this example. The right side is marked "THE PROTECTOR PAT.MCH.6.83.AUG.29.93" in a circle at the center. The removable left side plate is marked "CHICAGO FIRE ARMS CO. CHICAGO, ILL" in a circle at the center and has a textured border. The matching serial number is marked on the inside of the frame, on the side plate, and on the cartridge block. It has a checkered hard rubber plunger pad and matching side plate inserts. Provenance: The George S. Lewis Jr. Collection

Very fine, retains 85% plus of the bright, original blue finish with the balance having thinned to mostly a smooth grey patina, primarily on edges. The hard rubber plunger pad and side plate inserts are also very fine with a few scattered light handling marks and crisp checkering. Mechanically excellent.
