Just under 13,000 of these palm pistols were manufactured by Chicago Firearms Co. in the 1890s, with Flayderman estimating only 1,000 in the 3700-5400 serial number range to have blue finish. This example is very close to that range. 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 antique ivory side plate inserts.

Very fine, retains 70% original blue finish mixed with some brown and grey patina and a small patch of light pitting at the top of the plunger. The period replacement grips are fine with minimal handling marks and crisp checkering. Mechanically excellent.
