The Oxford was introduced at the Commercial Motor Exhibition of 1947, and a fleet of new cabs served to carry guests from the wedding of Princess Elizabeth]] and Philip Mountbatten (late Queen Elizabeth II and the Duke of Edinburgh) at Westminster Abbey in November of that year.

The prototype, designed by Morris-Commercial, registration number EOM 844 was built in 1940 and was fitted with a landaulette body by Jones Brothers of Westbourne Grove, London.

With its limousine configuration and open luggage platform beside the driver, it was in every other respect the same style as all previous London taxis.

The manufacturer's name as recognised by the DVLA, and shown on some Road Fund Licence ('tax') discs and V5 registration documents is Nuffield.

The 1948 instruction manual for the Oxford Taxicab makes it clear that this was a Wolseley model,[6] as does the manufacturer's plate under the bonnet.
