This nice set of handcuffs sold for $174.39 (Plus $10.25 Shipping).
1884 Bean Prison Handcuffs with working key. The first patented cuffs that allowed you to leave cuffs closed yet unlocked for easier use. Handcuffs are in excellent condition and work fine.
Key is not original yet it does work the locks. I had a hard time trying to decide if these where prison or patrolman cuffs. If you are an expert maybe you can tell for sure. These cuffs have not been cleaned. - eBay (15 Feb 09)
