I recently came into possession of a full Huret Jubilee set; both the front and long-cage rear derailleur look NOS (after some polishing), but it's clear that I need to do something with the jockey wheels as they feel very crunchy.
I was wondering if anyone has a link to an exploded diagram of this derailleur? I don't want to disassemble without one, I've heard these derailleurs have a propensity to explode into a mass of springs and tiny screws if one isn't careful.
Also wondering if anyone has made a side-to-side comparison with the short-cage. I assume the mechanism is the same, only the cages differ?
