About 400 TXM
Reverse dateless plates place the numbers before the original local index letters, so the registration carries local authority provenance without a year marker. The XM index mark traces back to London. This reverse sequence was issued from the 1950s onwards as earlier dateless runs became exhausted. At 6 characters, 400 TXM is a standard-length registration for this era.
