How old for B+W number plates?!

[pablouk79]

A strange question... Im getting my midget resprayed and cleaned up and really want some metal B+W number plates - its purely cosmetic, but wondered if there were any rules on the age of how old the car needs to be.

its 1973, if anyone knows then please let me know!!

Thanks
