After a weekend of tinkering and cleaning, I think I'm just about done.

Jobs completed:

• OA bath for all chrome parts
• Meguiars Scratch X followed by wax
• New Schwalbe Marathon Plus tyres, tubes and rim tape
• Grease/oil everything
• Treat saddle with neatsfoot oil
• Replace brake cables with NOS/pattern parts (they were at their limits, and one wasn't original anyway)
• Replace brake blocks with Kool Stop Continentals
• Replace SA driver with 3-spline type from 1980 hub
• Replace indicator chain
• Replace sprocket with 22T version
• Replace chain
• Replace nasty red & blue crimp terminals to rear lamp with plain metal ones and black heat-shrink

Jobs still to do (awaiting parts):

• Replace front & rear lamp bulbs with LED items
• Replace grips (in my haste, I cut off the old grips, thinking that they were nothing special. I now believe that they were the originals. I've fitted some temporary replacements whilst I wait for some NOS ones to arrive)
• Tidy the lighting cables using NOS John Bull rubber ties

You can see all the finished pics here, but a few to start with:
