Looks like a mid to later 80's derivative of the PH10 so Your P10LS identification might be a correct, or a very close one. I agree with GB about the fork crowns. Peugeot Carbolite 103 forks had the same tree pointed feature where the fork legs go in and the rounded. shoulders on the crown. The Carbolite 103 fork legs also had a very obvious seam (more like a square edged groove) at the back of the legs. Maybe they eliminated this seam by the mid 80's whe I think this bike was built.
It's sort of a base level sport model from Peugeot, but a very decent quality bike that should ride very well and is worth modding up with a bit better components than Peugeot originally installed on it that will further improve its performance.
