Very occasionally blank chassis plates come up on Ebay UK but I've never seen door plates, presumably they must be just for the Federal cars ?
On the topic of Andy Graham and history, I've also contacted him through email and he's a very helpful guy. My query was about my Elan and he told me things like when it was built, engine numbers, etc. He even found which dealership it went through to the first owner. Of course, being a history nut I then went out to buy some old car mags from 1968 on the off-chance that they had adverts from the dealer. (which they did)
So you see Mike, you're not the only one who likes to know the tale about your cars. I'm so hooked on the idea that a few months ago I finally tracked down a mint copy of the 1987 magazine that contained the original classified advert from which I bought the car. Now that's nerdy......
