A van version of the Series E, rated at 5 cwt capacity and designated as the Series Z, was produced from 1940 to 1954. While having an external appearance similar to the Series E, mechanically the vans were more akin to the Series II, still having a three speed gearbox. 

A barn find ex-GPO Telephones van finished originally in green livery and purchased from GPO Maidstone by the previous owner in 1965 and hand painted red and black. A 'wrong' Morris series E car front and telescopic shock absorber conversion was believed to have been fitted in GPO workshops.

​

The Morris was laid up in 1965 and returned to the road in March 2013.
