Registration numbers (number plates) you've never forgotten

First started long distance in 1967 for a local firm (New Milton) called A.Curtis & Sons. There were 3 Albion Rievers: 17 COW, 500DCR and ECR 332C all Southampton reg plus an ERF 8 legger: LOT677F and an AEC Marshall with an unremembered W.Sussex reg. A couple of the Albion reg nos would be worth a bob or two today.
