One dark blue Morris Minor Vans. The South Derbyshire Water Board had a fleet of these and were used by Watermen, Plumbing Inspectors and Water Supply Workers. The joke was that there were very few combinations of door lock and one key would open several vans. Later there were a few Morris Mini Vans.
