Lily Leg Irons

 Here is an amazing set of Lily Leg Irons. These are EXCEEDINGLY rare. They tend to have a very short chain, as seen above. This pair was listed for $495 or best offer and an offer was accepted. I have a feeling these were only up for a short time before being bought. At this price, I would have bought them if I had seen them. 

That is very cheap for what this is, although there is no key and the seller indicates that "the screw on the left cuff is stuck" which is hopefully just a bit of corrosion from being left unused for a few decades. These are shrouded/recessed threaded bolts that screw in to lock with a square hollow key. This would not be too difficult to make.

Above, detail of these beautiful cuffs and the locking bolts. 

If I bought these I would put a few drops of a penetrating lubricant in the mechanism and wait a few days while I made a key like device for this.
