FRONT DERAILLEUR:
Campagnolo Record - 28.6 mm clamp-on mount - "CAMPAGNOLO" logo on facing of the hinged clamp - aluminum alloy body, hinged clamp, upper and lower pivot arms - chrome plated steel cage with stylized "Campagnolo" logo on its outer facing - post 1967 without cable stop - post 1972 with enlarged pivot post housings - pre 1973 without circlip on upper pivot - pre 1978 non C.P.S.C. compliant "flat" style outer cage plate - model 1052/1 ... [Correct and original, however, it should be noted that this particular front derailleur features the rather odd combination of a third edition Record body having enlarged pivot post housings but without a circlip retainer at the back of its upper pivot post. To the best of my knowledge, this transitional model was only produced for a brief period during late 1972 immediately prior to the release of the "normalized" third edition Record front derailleur having the very same body as seen here, but with an extended upper pivot post to accommodate the addition of a circlip.]
