I aquired a frameset recently with no decals or headbadge, no identifying marks of any kind. Here's what I know. The bottom bracket is French thread. It had a mix of European and Japanese parts eg., a Simplex downtube shifter, Weinmann Vainqueur 999 centerpulls, the old kind that are engraved with the name, Mafac brake levers and the rest was Japanese stuff. The Suntour derailleurs date to '73 and '74. I don't know how long that style of Weinmanns was produced.

There is a frame number and the head lugs look familiar. I am going to try and upload photographs. If anyone has an idea, I'd appreciate any info.

The last year for the Weinmann center-pull brakes with stamped name was 1964. The only major French brand I'm aware of that spec'd SunTour derailleurs in 1974 was Motobecane. Of course, one or the other is not OEM and we don't know which so I'll be awaiting pics and the serial number.
