I can't tell you tell you how awsome this lock is. It weighs almost 3 1/2 lbs. The old army prison at Fort Leavenworth, Kansas, became the first United States Federal penitentiary in 1895, until a new facility was built by inmates in 1906. This lock is from around 1896 from what I've been told. A real collectors piece. I only accept PayPal or a money order for payment. Please add $7.00 for shipping.
