I'm trying to get info on a recent acquisition. A red Lejeune, I dunno what. No blue on the head tube. Late 60's?? There is a Simplex threaded dropout with Campy NR derailleur dated 72. This had to be tapped out, right? Also the frame is stamped 67 A on the bottom. That's it - 67 A. There is residue of a 531 decal on the right front fork. A TA crank and PHILLIPPE PROFESSIONNEL handle bar. MAFAC Racer brakes. Cool braised on rear brake hanger at the seat post clamp. Any idea of the date or model of this bike? Thanks, George
