Thanks again for all the replies. All the bits are now off the bike apart from the right hand crank due to a stubborn cotter pin. It's resisted my light taps so far, so I'm going to try and knock it out on the weekend once I can get it properly supported. Everything else came off really nicely - it's true what they say about build quality being a thing of the past!
First bits of chrome have been polished up, and they have come up lovely. A good wash and a compounding of the frame and mudguards next, though I get the feeling the dirt might be hiding more rust that I'd like!
Still can't post photos I'm afraid, but as soon as I can, I will!
