Since the report above, I discovered that it wasn't the radiator at fault as it still filled-up No. 1 cylinder with water. I removed the head and discovered that Vinnie's original fear that the crack in the block had migrated through to the bore was unfounded as the bores have been lined. Instead, I found a break in the head gasket between No. 1 and a water way. I set-to and replaced the head gasket, all the valve springs, all the exhaust valves and had the head lightly skimmed. I then started it up and all seemed fine. In the interim, Whimsey also now benefitted from a complete re-wire and some new tyres. Unfortunately, though, after a very short time, the head gasket went again. This time, I took no chances! I had new gaskets made (solid copper) in 1.5mm thickness, requested that the water-jetters didn't de-burr them and then turned all the edges over with the shank of a screwdriver. This, of course, was AFTER I had it properly annealed (I didn't anneal the last one, assuming that it was new(ish) from Ian Polson but I suspect they've been kicking around for a while and should have been). Once I'd done what I could with the gasket, I applied Wellseal and put the head back. It has lasted longer this time and is still holding up so I hope this is now sorted.
Whimsey is much nicer to drive than the Fuggle truck, the gear ratios are closer together (third and top anyway) and, joy of joys!, a taller rear axle ratio. This does make reversing up hill a challenge so I will just have to remember not to get myself where I need to do that. The steering is also lighter (wider tyres?) so it's actually a joy to drive!
I now need to get to grips with folding the and stowing the hood properly!
