Chris ... laminated plastic for the new style plates and have to have certain printing on them ... the black plates most people go for are pressed aluminium with slightly raised letters/numbers ... I think they look the best (other opinions are available 🙂) ... but they range from that to painted on wood/metal backing to being hand painted direct on the bodywork on some oldies.... never heard of a genuine old black plate car being hauled up for it's plates (tho some modern cars with poorly spaced letters to try and spell a word do get pulled along with too small and 'fancy' plates ... but they're just dead illegal with no question)
Paul ... nothing to stop you putting 'modern' plates on a historic as far as I know (unlike the other way round) ... though I think if there was to be any restriction rolled out the plates would just flag up as 'registered historic' on the cameras for enforcement purposes by number irrespective of the style.
No sign of any restrictions here so far (though who knows if some green politicians sense an easy headline?) ... some other countries do have restrictions I believe and you could see the likes of the German carmakers strongarming their Govt into banning all cars over 5 years old to keep their sales up 🙂
