Sweet, are you sure that the DMV gods didn't look kindly on you?
My now sadly ex US black teener when registered with DVLA on import was allocated a period correct plate from the database of non issued ones - KVW214N. Someone at DVLA must have know a little history of the 914 in general as there is no way the result was a total coincidence
KVW - obvious for those in the know
214, guess 914 had been allocated
N designates year of original construction mid 1974 - mid 75, so no choice there
