Hiatt Darby style cuffs what are they worth

Hi I bought a set of leg irons and adjustable handcuffs directly from Hiatt back in the mid 1980s They are the screw type lock, with a very good finish and fine workmanship. They have Hiatt stamped on them. But they are lighter metal than steal ones. Could anyone tell me what they might be worth? Thank you DGS

You don't say if they are Unfinished or Finished either (Nickle Plated or High Polished?). But generally since these items are Readily avialable from any number of sources.. Adjustable Darby Handcuffs.. $35.00 +/- Leg Irons $52.50 +/-. I think these prices are reflective of todays retail. Now Putting them on Ebay, Now That's another story ++ or -- !!
