My 1976 (I think) Moto pamphlet has the Grand Jubile in red and the Grand Record in black (both also available in silver). The pictured red G.J. looks very much like the frame in question. The pix of the bikes show nearly identical frames, tho' the triangular 531 sticker is just visible on the G.R. Specs for G.J. say "Reynolds 531 double butted, forged tips." G.R. is "Reynolds 531 double butted tubing throughout, Campagnolo tips." G.J. is spec'ed with Stronglight & Huret or SR & Suntour drivetrain. G.R. is, of course, TA and Campagnolo.
