I've had the rear wheel rebuilt, as it was in a dreadful state, and it's now in primer and, when the weather warms up a bit and it's less damp, I shall be repainting it soon I hope. Then I shall have a rolling frame and working on it will become much easier than it is now (propped up on bricks etc!).
Once it's relatively 'mobile' I'll put the engine back in, then begin rewiring the bike. That should be interesting...!
