Vintage French Leg Irons, complete with key. I ship worldwide. - eBay (10 Dec 2009)
Here ia a more details English description from a previous listing for this same set of leg irons which had an opening bid of $299 but did not attract any bidders:
This set of leg irons had a high bid of 138Euros / $198 (Plus Shipping).
This auction is for a rare set of vintage French Leg Iron, or Restraints, probably from the French penal colonies like Guyana. They are similar to the Rivolier type, if they're not made by Rivolier. They come with a working key. I understand the middle ring is intended for overnight lockdown. The locking mechanism is a screw that is simple, but very effective. They work fine. A very rare restraint, or handcuff. Slave restraints, handcuffs.
Shipping is $22 to the US, all others pay actual shipping costs. If you win any other of my auctions, those items ship at no additional cost. - eBay
