I have a pair of Hiatt Darby handcuffs stamped "1894" and a key that is too short to reach the bolt. The key has threads in it which don't match any standard tap that I have, so I'm in the position of trying to figure out how I can get a working key. The cuffs themselves are in great shape, and we want to use them as part of a display inside an old jail that a group of us are restoring into a little museum (in a ghost town in Arizona, USA). Anyone have any ideas how I might be able to get/make a working key for this model?
Thanks for the pointers... I'll check out the possibilities from both Cannon and McColl.
To answer the other question, these cuffs are stamped "HIAT" and underneath that "BIRM" on both cuffs (although the surface is curved, so it appears that the final "T" didn't get stamped). They also have a stamp to the right of that which has "M & C" on the first line, and "1894" underneath that.
Also, on the hinge strap is the number "156" stamped on both cuffs.
Opposite the keyhole on the barrel is a circular pattern of "Y"-ish looking stamps, with a final "Y" in the middle of the circle. Those are the only markings I can find on them.
