Not sure if this will help any, but it is a Dunelt "Racer" model - really vivid green color with black accents . Serial Number on frame is 83390. Huret Derailleurs front and rear. Campagnolo bar end shifts. Weinmann center-pulls. Wright saddle that looks like a knock-off of a Brooks B-17 or B-15. 27" x 1.25" wheels (pretty sure they're aluminum). 40 spoke Atom hub in the rear (I'm not going to have fun replacing it).
Any insights or clues would be much appreciated. I'm not even sure what year it is - whether its from the '70's (which is my suspicion), or the early '80's. I know its rather sad that I know so little about one of my bikes, but this one is outrageouusly obscure.
