Couple of RB-1's passed through The Lab this year on their way to new owners:
A 93, that I picked up as a bare frame several years ago. Took a couple of years to find all of the tricolor bits in the right condition. Love the biplane fork crown.
An 88 that was purchased whole from the second owner in very good overall condition, but the real gem was the almost-perfect frame. It made a great basis for a lovely 10 speed Ultegra 6600 group build with custom wheelset.
