Toy Handcuffs

I've included these only because I've never seen them before and they're clearly vintage. They were made in England. These are a novelty item. It looks like they have release buttons on the side of the lock cases. They did however include working keys. Clearly there is no double lock or swivel. In fact the connection is simply a small, bent S link. 

Sold for $16.37 after two bids.
