About 66 GRM
Reverse dateless plates place the numbers before the original local index letters, so the registration carries local authority provenance without a year marker. The RM index mark traces back to Cumberland. This reverse sequence was issued from the 1950s onwards as earlier dateless runs became exhausted. At 5 characters, 66 GRM is shorter than most registrations in this era.
