I picked up a Peugot at a yard sale yesterday. I've narrowed the years down to either a 77 or 78 by the decals, but I'm wondering what model it is and whether or not it has any value. It says Cadre Allege, but doesn't seem to have any other markings that would say what model it is. I'm guessing it's fairly low end as it has simplex Stem Shifters and Suicide Levers. Additionally, it has Center pull brakes that say Weinmann 610 and Vainqueur 999. It has a three piece crank, it's 10 speed, and it's rims have vertical lines on them. any help would be greatly appreciated.
