Thanks Paul, that's easier than I thought. I'd expected to spend a day driving down to Luton to have someone look at the chassis number. Does seem daft to do that as it's now part of the MOT test to have a mechanic check the numbers.
I'll have to check with my insurance company about the speedo. While it's a legal requirement to have it in mph, it's not something that gets checked at the MOT.
Your insurance seems a little expensive. My UK RHD GTL is £120 with Direct Line as a normal car with comprehensive cover. They don't like more modern LHD cars though. Performance Direct quoted me something half sensible for my nutty Gordini powered R4 project (£250 ish for every day and business use). I'm with Hagerty for my LHD '65 car as they aren't in a hurry for me to get it registered in the UK - lucky as the engine is out just now. About £120 limited mileage but I can't drive it to work. They've invited me to a Classic car meeting. I'm astonishingly old though - nearing 36.
Did you end up buying the white car from Anna?
