door escutcheons

Hi all again, well the new wheels arrived but havent even had a chance to fit yet due to some family troubles but while i am chiling out thought i would ask about this. my mini is a 93 cooper spi with a few changes here and there(k and n filter, wide bore exhaust etc..) but the one thing that i wondered about was the door guards as they are etched up with the rallye montecarlo 1966 markings.I havn't seen these anywhere else and wondered if they are standard or does this make my "billie" a bit special? (it is anyway regardless as its mine but just wondered if they were a rarity?)
