Help identifying an old frame

We finally decided to "do up" an old bike we had laying around. I guess it is from the 70s given the Shimano thunderbird mech. Fairly light steel with Shimano stamped on the fork drop outs. The only other marking I can find on it is NERVCR stamped on the fork steerer. It also has a frame number on a slightly raised plate just below the seat clamp. Not much to go on, but any ideas? Thanks

    Nerv = nervex, French manufacturer of lugs so probably decent quality. Might get more joy posting photos over on Retrobike?
    Make mine an Italian, with Campagnolo on the side..

    Thanks. The mystery deepens though. We started to remove the white gloss paint (no really) from the frame, covering the original bronzy-orange, and the lugs on the headtube have BCM stamped on them, which I believe were made by Bocama? Anyway looks like there is a nice frame waiting to escape. It'll go in the loft now until the winter and hopefully emerge as a classic single speed in the spring.
  • Bocama defo says France, and a lot of French manufacturers of the time were, in fact, using Reynolds 531 and 753. Motobecane, Puch, Peugot, Gitane ... or a small framebuilder/custom job.

    Thanks, living on the French boarder, that connection makes sense.
