hiatts 3020 aluminium nickel plated finish

I just got a pair of old in the box hiatts snap on aluminium handcuffs and they are nickel plated and very light they also have push button double locks like the (i think 2020) I have never seen a pair of these and want to know if anyone nows more about them thanks

I also have this cuff.
The 3020 is shown exactly as you describe it in the 1986 Hiatt catalog.
The 3010 is the same model, but without the extended DL buttons.
The 2020 is Nickle plated steel with extended DL buttons.
The 2025 is Black Steel with extended buttons.
All of these are the earlier model with 3 ratchet teeth on the movable pawl.
