Frame is not available, not in same State. I remember the old group was Campy Gran Sport/Nuovo Gran Sport. The whole bike was repainted at least once. Only chrome: 1/2 socks on chains stays; rear dropouts are Simplex w/eyelets (might be long), plain stay caps, "58" stamped on lower head tube lug, "75" stamped on seat tube lug, BB shell 68mm, BB 1.37x24, 3 Campy clamp-on TT cable guides, braze-ons: BB shell and chainstay cable guides, DT shifter and bidon bosses, no serial number.
Odd that a fork with Campy ends would mate with a frame that has Simplex DOs plus the other details with assorted guides but clamp-on TT clips makes me think it's a Richard Sachs fork planted on some (entirely) Other Brand frame...but maybe RS was quirkier that I imagine!
