Nick, I don't know if the Bentley you mentioned is "Old Number One" or not, but a few years ago there was a huge legal row about it, and whether or not it really was ONO at all, and even if enough of it could be traced back to ONO to establish a reasonable legitimate claim. I think there were 2 cars, both with very tenuous claims to being ONO, as both had been so modified and replaced over the years. like the Woodman's Great Great Great Grandfather's Axe, handed down for many generations, with 7 new handles and 5 new heads!
