La Massonette handcuffs

 

These French handcuffs sold for $75 after 1 bid. They are only single locking. They have Clejuso style (bent steel saddle riveted to cuff body) clevises, a long chain, two o rings but no swivel. 

An interest facet of these French models is that the wrists are held in a different orientation than most other handcuffs. Aside from the long chain on these, which negates the fact, French handcuffs often hold the wrists perpendicular instead of parallel. You can picture this if you imagine the chain shortened to 2 O rings.
