So, how is rotation limited on the one for Huret DO's?

Second: I recently became the owner of a Jubilee RD meant for use with a Huret dropout. This derealleur came off a Motobecane Grand Jubilee frame and, unlike the other RDs I've seen on these bicycles, it is a long cage variant. Despite that, the freewheel on the bicycle was a 14-28.
Third: If we never get the full story for some of these anomolies, I will not be surprised. Cheers, Fred Rednor - Arlington, Virginia (USA)
