Hiatt Irish 8

 This is a very nice steel Darby restraint from Hiatt. The Irish 8 is an extremely restrictive restraint, and can be worn in multiple ways. 

They are marked Hiatt and British Made. The current bid is $4.25 with 3 bids. 

UPDATE: SOLD for $140.50 with 14 bids! Happy to see it go higher than I expected.

Unfortunately this cuff doesn't have a key. This is a nice restraint, though, in great condition. 

These are pretty rare. I'm gonna guess they sell for about $100 though, because there isn't a key. 

For comparison, here is the modern KUB model made for Chicago Handcuff Company (Handcuff Warehouse.)

Although their Darby style restraints section has dwindled over the years, a huge of buying from Handcuff Warehouse is that they specified two keys from KUB. Most other sellers, including Cuffstore, only supply one key.
