Changed the inner ring on the Ron Cooper crankset to a 39T and gave the brakes an inspection and wipe over (they feel very smooth so I'm not taking them apart) and fitted new pads. They're Shimano 600 SLR sidepulls, with the thrust bearing and nylon spring bushings, and they are absolutely perfect in form and function. Sheldon Brown always thought the SLR sidepulls were the bee's knees; dual-pivots have a simple screw to centre them but, apart from that, are worse in every way.
The whole groupset (Shimano 600 "tricolour" throughout, except for a Dura-Ace headset) is now cleaned and ready to refit, although I still need to rebuild the wheels. DT Revs for the front, Revs on the left at the rear and Comp on the right. It will not be a quick build, as Revs wind up like nobody's business. However, they do make an exceptionally good wheel; I built the front one on the Fuji 13 years ago and it's never gone even half a mm out of true, despite crashing through potholes that made the frame creak.
A little bonus lurking under the dried-out tyres was a pair of perfectly good pink Vittoria latex tubes. Personally, I'd have had better tyres and stuck with butyl tubes, but someone wanted to go fast.
