About 321 OO

Reverse dateless plates place the numbers before the original local index letters, so the registration carries local authority provenance without a year marker. The OO index mark traces back to Essex. This reverse sequence was issued from the 1950s onwards as earlier dateless runs became exhausted. At 5 characters, 321 OO is shorter than most registrations in this era.
