I am not quite an expert but have been doing some research over the last few weeks into what model my 70s Peugeot is. I can therefore tell you this much---from the paint scheme and brakes this looks to be an early to mid eighties model, which you can confirm yourself by looking at the serial number on the BB. 7 digits means 1970s, 8 digits means it's 1980s. Peugeot seems to simply have used whatever stickers were lying around though, and their method of naming models is based on French logic. Have a look at the following site to help you get a bit closer to your answer. Pay attention to lugs, paint scheme, brakes and frame material as well as the colours-different models had different colour schemes.
