Many vehicles produced by Harbilt Electric Trucks were classified by their payload, which was measured in hundredweights, and this usage has been retained in the article.

A number of 790 tow trucks were supplied to the airline Pan Am for use at Heathrow Airport, while customers for the 685 power units included Leyland Motors and the Scottish company TPS.

Their first design, the 735, had been built in 1956, and one of the earliest examples was bought back from the dairy who ran it, and is now part of the Leicestershire County Collection.

Options for bi-fold doors or roller blinds to seal the exits were available, as were produce cupboards, for the storage of other products besides milk.

The payload was reduced to allow it to travel at faster speeds in urban traffic, and 30 were supplied to the United States Post Office for mail deliveries in Cupertino, California.

[13] The vehicles were supplied in March 1974 as right-hand drive chassis, with the bodywork assembled in Scotts Valley, California and this model was officially the HSV3.

[14] In June 1972, Harbilt bought the Douglas company, a manufacturer of electric trucks and tractors, moving production of these vehicles to Market Harborough.

Morrisons had moved from Leicester to Tredegar in 1968, as part of a government plan to replace jobs lost in the coal mining industry.

Under the agreement, production of milk floats would transfer from Market Harborough to Tredegar, and Morrison trucks would be handed over to Harbilt.

This included some Manulectric trolley trucks, but details of the deal and the precise dates are a little sketchy, as a copy of the agreement has not been found.

Although they had administrative offices in the West End of London, enquiries about electric vehicles were still channelled to Market Harborough, and the Harbilt trade mark was retained.

[17] British Steel Piling (BSP), who were based in Claydon near Ipswich announced in December 1971 that they would be buying the Crosby Valve group for £1.8 million.

[18] By late 1974, Crosby Valves and Edward Le Pas had decided that they wanted to concentrate on other products besides electric trucks.

The offer was accepted, and production moved to Corby, but Davies failed to win any MoD contracts, and lost interest in building electric vehicles.
