I happened to notice this patent number stamped on
the inside of one of my model 3 peerless handcuffs.



It is stamped on the outside in the normal place also.

Has anyone come across a pair with the trademark stamped on both cuffs
or both sides of the same cuff?

is the thickness also different on the double arms?as it looks in the photo one side looks thinner on each cuff?

both measure .107 inch or approximately 2.75mm thickness.
