This is a very interesting and unique Colt T-12 single shot prototype pen gun. It is theorized that weapons of this type might have been developed or employed by early OSS/SOE or later CIA espionage agents. The pen gun functions very much like the current Stinger or the pen guns that were used throughout the Cold War era of the 1950s and 1960s, however it's an extremely small or miniaturized version that fires a 12 cal. cartridge. The overall length of the pen gun is approximately 2 inches, and it has a 1/2 inch barrel that unscrews on the front end. As you can imagine, it is extremely small and can easily fit into the palm of your hand or a shirt or pants pocket. The gun functions or fires by unscrewing the barrel loading a single cartridge and then just retracting the cocking knob located on the side of the action which is screwed into the fixed firing pin and either just locking it in to the safety catch or releasing it to fire the cartridge. The body of the pen is machined steel with circular cuts on the front and rear section of the pen to aid in gripping the weapon. It has a brass end cap. The side of the pen is marked "COLT T-12". It is housed in a small wooden storage box that measures approximately 2 1/2 x 1 1/2 inches and has a white paper label on top that reads ".12CAL COLT T-12/US PROPERTY". It has an all blued steel finish and is complete with two brass dummy (non-firing) display cartridges.

Excellent. Showing no use or firing that we can detect. The wooden storage box is also in excellent condition. Certainly a very interesting and unique, one-of-a-kind or prototype weapon that very little is know about that warrants further research into its history and development.
