Can you help to identify these frames, bikes or parts?

Anybody got infos on Mercier? I got this frame for a while now laying around, still searching for info on the year, parts and decals to fit.

It has Campagnolo drop-outs, so a bit unusual for a french bike, and no eyelets. bad paint job, so I think it was repainted. Another strange thing are the cable housings on the right downside of the top tube, haven't seen this on any other Mercier before.

I will build it up with Shimano 600 Arabesque as the back brake will fit best this way. The whole set weights ~2900g, so I think it is made of Reynolds 531 or some kind of Columbus steel but the diametre is 26.4mm or .6mm, so probably no 531 or SL.
