Several years ago I had an email conversation with Skip Eckhart. My 82 614 (I think), N5F4C88. Pewter gray with only seat tube panel (slate blue). Suntour dropouts w/eyelets , brake cable braze ons, long chain stays, glue on head badge, rear rack braze ons, bottom bracket cable braze ons (on top). Had a triple when I received it used. 531 main tube decal. I can't remember what else to note but that was most of the "tells".
