[NOS - from a cosmetic standpoint, this component is near perfect excepting a couple of very light markings to be found on the backside of its body (...these are only noticeable when viewed in just the right light and at just the proper angle - most people would not likely notice their presence except upon close inspection, and in any event, they will prove even more difficult to discern once this derailleur is properly mounted onto a bicycle frameset) - introduced in 1977 and subsequently produced as seen here through 1983, and thereafter in essentially the same configuration absent any Simplex "starburst" logo on its outer cage plate, the SLJ A 522 superseded the SLJ A 500 as their top of the line competition / racing front derailleur - this particular variant was also the first C.P.S.C. compliant design front derailleur to be offered by Simplex]
