Are steel 3 pin stronglight cottered cranks of any collector value? I can't find any for sale anywhere or on ebay. I have a line on an old crescent with nervex lugs and 531 frame, it has these cranks on it. I would only buy the bike (or part of it) for the headset (record) and saddle (ideal) and flip the cranks if they are worth anything and the steel titan stem.
