Is this derailleur on-topic ?? If not, it's the best imitation of an on-topic derailleur I've ever seen ...
(depicts a 'Sunrace 555' which for the life of me looks like a titlist or 1st-generation shimano-600 derailleur, titlist being 0'th generation ... even the box is a clone of the late 70's yellow shimano 600 and dura ace boxes ...)
