Harvey,

Good explanation.

These Mafac pulleys were used on a lot of French tandems as well as mixtes. Hooking them up was a test of spatial relations and twisted logic. I remember threading the cables on a number of them but I couldn't recall how they went together. "Is it wrong...or just French" ;-)
