Here is the model 8 leg iron from Clejuso. Clejuso produces high quality heavy duty steel restraints.  These sold for $66 after 15 bids, with two original keys.  This is a good deal for the buyer. Handcuff Warehouse currently has these for $172.50 although they can be found from other sources, particularly in Europe, for €99 or so.  I bought a pair of these new from Handcuff Warehouse in 2021 for about $100, and even then they were delayed in shipping for quite some time.  Above, close up detail of the makers mark stamp Clejuso No.8 Germany  Above, view of the reverse of the cuff body. Note the standard Clejuso clevis and the quality and weight of the cuff.
