I confess I'm somewhat lost. I'd like to see the bike; you might take a look at the catalogue link I gave and see if anything matches up. Even seeing it, I have no idea if I'd be able to identify it; my post 1980 Peugeot knowledge is limited, most of what I know is within the timeframe of my Peugeots (roughly 1967-80). Frankly, any double butted steel frame is worth something; probably a little more if it's lugged, but still worth something. Double butting generally indicates a middle-to-hi end bike.
