Okay, this seems kind of silly, but I've done a lot of research on bikes and components (not to say that I've done any more than anyone else here) and I have found no other example a SunTour Cyclone dérailleur quite like mine. The only difference between the one that I have and all the other first gen. Cyclone is that mine has a very distinct lack of black paint on the outer plate. This is a NOS dérailleur. It has no trace of paint anywhere. It was never there. If anyone has ever seen this than tell me and I'll stop wondering, but if I have something that will have Japanese collectors drooling over their checkbooks than I want to know.
