About 17 SUM

Reverse dateless plates place the numbers before the original local index letters, so the registration carries local authority provenance without a year marker. The UM index mark traces back to Leeds, now associated with West Yorkshire. This reverse sequence was issued from the 1950s onwards as earlier dateless runs became exhausted. At 5 characters, 17 SUM is shorter than most registrations in this era.
