About 400 MO

Reverse dateless plates place the numbers before the original local index letters, so the registration carries local authority provenance without a year marker. The MO index mark traces back to Berkshire. This reverse sequence was issued from the 1950s onwards as earlier dateless runs became exhausted. At 5 characters, 400 MO is shorter than most registrations in this era.
