Best I can tell it's a PR10 as there is a small remnant of the Reynolds 531 decal on the seat tube. BB # is 0542867, indicating 7 digits and a '70's frame, with "0" suggesting 1970. Square head badge says it's '71 as do rest of the decals match up from what I've found on line.

Stronglight crank, pedals, Mafac brake calipers, Ideale saddle, Normandy large flange hubs, and Simplex bits like drop outs, skewers, top tube cable guides, and derailleur cable guides all look right for the model. Suntour shifters and derailleurs are period correct, but are not original. Shimano brake levers gotta go.

Original paint and decals, will need clean and detail. Not sure what my plan is here. I bought it because my very first nice real 10 speed when I was a kid was a white Peugeot.
