American Munitions leg irons

 This pair of leg irons sold for $99.99 with no key. 

The key is a standard modern key. 

This is the leg iron being produced before the American Munitions Company became the American Handcuff Company. 

This is a simple, robust, heavy, modern ratcheting swing through leg iron. The straight link chain is rather heavy, and the rivets are exposed. This example has some discoloration from packing tape.

Here is another example. These are a transition model, produced after the American Munitions Company became the American Handcuff Company, but before they retooled their designs to the rounded, radiused, more refined design. 

The starting bid is $49 and there is one American Handcuff style key. These do take a modern handcuff key, but the company produced their own keys that have a distinctive tapered barrel. 

These also include the original instructions. The finish looks like it will shine right up.
