This question came up on another discussion group. Someone had bought a NOS Helicomatic freewheel to later find it had a diameter of 32 mm versus the 26 mm which was the Maillard/Spidel standard. Nobody had ever seen this odd "new" version. Here are a couple photos which had been posted on the BikeForums (Classic and Vintage) group.

Definitely stumped me. Has anyone ever seen the freewheels intended for a larger diameter hub... yet with the same style "helico-" threading?
