About 640 SGX

Reverse dateless plates place the numbers before the original local index letters, so the registration carries local authority provenance without a year marker. The GX index mark traces back to London (SE), now associated with London. This reverse sequence was issued from the 1950s onwards as earlier dateless runs became exhausted. At 6 characters, 640 SGX is a standard-length registration for this era.
