Well, I've calmed down over the weekend and decided it's not for me! The asking price was £200 but a quick Web search suggested £50-£100 would be nearer the mark.
I read the radiocraft restoration pages and as it involved melting pitch, and I'm not allowed to "melt radios" in our brand new kitchen, I'll let someone else take this one.
I can see, though, that such an amazingly iconic set will be snapped up quickly. I'll just have to wander around, nosing the air, until I smell burning pitch!
Thanks to all for your inputs, I'm going to ask more questions around the television display at Golborne.
