From the research I've done trying to identify my own Peugeot frame, that number suggests a 1988 model. Also from my research, you might find it "interesting" to get a positive ID given that it's been resprayed since most of the info I've found suggests that the only real way to work it out is either from the sticker on either rear dropout or BB shell (this would have the model on it, but likely gone with the paint job) or to find your year & then compare colour scheme/tubeset/groupset to pictures in the Peugeot catalogues on a site like Peugeotshow dot com.
I think your best hope, seeing as you bought it when it was likely only a few years old, would be to go through the '88 catalogues and compare the suspected original parts on your bike to what was standard on which models in that year. Hopefully you can get date codes off some and see if they correspond to either '88 or even '78 (Although I don't think Peugeot used a letter prefix on frame numbers prior to 1980 hence my suspicion of '88 ), that would make them more likely to be original then. Weinmann were good at putting the date on brakes etc)
