KH was an easy one to remember in the area I grew up in, representing (Kingston upon) Hull. Most of my Dad's cars included that in the reg. The mayor had similar of course.
I still have NKH1V, which was issued on my MGB in 1980, before they got wise to it and stopped the low numbers going out automatically. It was from Armstrong-Massey, the BL (and RR dealers) in Beverley.
