Unique Darbies

An interesting set of Darbies, eh?

From the Paul Daniels Auction. Did you win them Joe?

No.....but I am curious about them.
 They are listed as "tricked"...and I wonder who made or supplied them to Paul?

I have seen this set somewhere before, but I cannot recall where? I know it was some time ago, though. Great looking set of cuffs!
I would love to see their gimmick and how it works!
