Hello everyone,
this is my first post. I love this forum! now, on to business...
I recently bought an old frame in not the best shape (someone tried to make it a mountain bike i think) but it has beautiful lug work and Im almost certain its 531. problem is, theres no head badge or any decals at all. only thing i have is the serial # on the BB: 71f048942. also, it was painted flat black, but i managed to scrape off some of the paint to reveal a nice green color. My friend thinks it may be an old Puch due to the green, but it had a lot of French comps on it (some of which MAY be original: mafac racer front brake, huret spacer in the rear dropouts, nervar cranks). Ive been scouring the web trying to find a picture of it, but nothing. I think its probably late 50s/early 60s, but again, not sure.
I know i need to post pics to really get some help, but my roomate is gone with her camera, and I dont got one. Ill post soon though.

Thanks for all
