what seems curious to me firstly, for an 83 is that it is lugless, but i guess thats because it was from france not canada. it seems that peugeot didn't/wouldn't use that interior lugging or whatever it is called for outsourced production. looks in really good shape, & your touches haven't hurt. if t-mar's guess is correct it is entry level club bike, but don't be afraid to make reasonable upgrades, as you remarked. like bigbossman stated, upgrades wouldn't be foolhearty, & the ones you made look cool. the frame was the same from the entry level to mid level.(pretty much) but the crankset shows it is barely worn-in, so upgrade for looks or weighloss for now...nice one (this isn't a classic, so modernizing it is cool man!)
