I learnt a few things last night
The bike was originally RED (as already pointed out) - I can not understand how it went so orange, I suspect it may have had some life in the sun, it may explain the cracked/raised paint - as all the drive train/brakes etc are in a good condition, or the bike just spent its life in a garage/shed, being knocked about.
T-Cut works to clear the grime off, but did not have a chance of restoring any colour - no surprise there
It is VERY easy to get new tyres on / off old wide rims
It may not be wise to use the old inner tubes, as when you pump them up hard, explosions can occur
- my wife thought I was in a garage incident!!!
"Modern" wide tyres 2.1in, are a VERY TIGHT fit with U-Brakes, I have clearance of about 2mm either side, don't fancy any muddy rides
It took my modern (disc enable) rack no problem
The seat post is not stuck in the tube, however I regreased it, and now I can not tighten it enough to hold the seat in place, I will need to remove excess grease, maybe make a shim?
It just needs a new inner tube and its ready for duty - looks beefy, but heavy, looking forward to giving it a run out.
