Under 13,000 of these pistols were manufactured by the Chicago Firearms Co. in the 1890's. Only an estimated 1,000 had a blue finish. 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.

Good. 40% of the original blue finish remains, and the balance has an aged patina. There are some damage visible including gouges on the side plate edges. The pad and side panels are also fine with mild aging and handling wear. The action is fine.
