About 157 X
Reverse dateless plates place the numbers before the original local index letters, so the registration carries local authority provenance without a year marker. The X index mark traces back to Northumberland. This reverse sequence was issued from the 1950s onwards as earlier dateless runs became exhausted. At 4 characters, 157 X is shorter than most registrations in this era.
