Re:
I think now, Brocklanders, you and I have almost exactly the same 'matching pairs', as I've my glacially slow rebuild of an '89 yellow/white Clockwork and my original (as in I bought it from the shop floor in '92) Prestige in orange/white.
The latter was from about Feb '92 (certainly before May/June as I rode it to school for my GCSE exams that year) and has the Ritchey Logic Tange Prestige SuperTubing.
Watching with interest!
