Here's a very unusual and extremely rad little frame, custom made by Witcomb British Lightweights in the early 80s.  This had been in storage for over 20 years when I found it!  Full Reynolds 531 tubing, with long point lugs, fillet brazed rear end, double RD cable stops, and top routed BB cabling.  Half-wrap seatstay caps.  Long Campagnolo dropouts with eyelets for fenders.  New Velo Orange Grand Cru headset.  Paint is in remarkably good shape, although there are a few scratches and chips from normal usage.  Some of the decals have cracked and chipped, but the manner in which they've done so actually adds a really great patina to the frame.  Keep in mind that Richard Sachs learned his craft from Witcomb - you can see some of the details that influenced his style right here! 

Critical numbers:

Seat tube: 47cm (49cm Center to top)  /  Top tube: 52cm  /  Rear spacing: 126mm
