The Post Office Telephones Service van harks back to those days of state monopoly when you had to have your phone supplied by the GPO and however much we moan about the serve we get from the rather dodgy companies supplying telecoms these days it was nothing like the nonsense we used to have to put up with then - it was actually illegal to wire yourself an extension phone and you could only rent handsets of approved design from the GPO - I think there was a choice of one. It also took months to get a line installed and if you didn't like the service it was just tough. Well, when an engineer did eventually arrive they would be in a dark green van like this one - camouflaged I guess to avoid the wrath of their customers.
The Dinky van was in the range from 1955 to 1961 and was always dark green with black trim and a silver ladder on the top. It is a model of the Morris Z van derived from the pre and post-war Morris 8 series E, the predecessor to the Morris Minor.
