m m at least we know the style of the 'B ' head tube badge is sound. thanks for that thread.
could not see if the fork crown was pantographed on the frame in question. perhaps a close up could be shown.
Its interesting that in 1984 they used a concealed rear brake cable the very same on my lemond glx 1993.r
but the frame in question shows an older[ planted on] along the top tube routing
i wonder if this is because it is 531 and there was a confidence issue regarding tubing wall thicknesses[not wanting to fabricate holes in an unfamiliar product] we know they used different fork crowns on the the gan s so they may well have used whatever bb shells they had at the time as well as lugs.
