I always get a set of numbers off the internet (not necessarily in the correct order) and stick them on in the correct order I am not making up a number plate if I buy one thats a PR27 and comes blank I just add numbers to it then I lacquer it in time honored manner if I was a good detail painter I would paint the numbers on. I dont belive in those actions I am breaking the law which applied to post 1st Jan 1973 vehicles. I note recently that there is a bit of additional legislative tom foolery which has been added stating that it needs to be an historic vehicle but I cant see many people with pre 73 modified vehicles changing their plates can you? and I think thats a descriptive 'chancer' by a .gov script writer and has not been enacted in law which because of the rolling nature must still say 1 Jan 1973
