In October 1931 motorcycle manufacturer A.J.S. went into voluntary liquidation. At the time they made sidecars using the 'Graiseley' name. Walter Vincent Ford, Diamond's managing director, was approached by Alec Holder, who had worked for Clyno as a draughtsman, and Harold Nock, who later acquired D.M.W. with the idea of acquiring the A.J.S. sidecar business in order to manufacture sidecars and supply them to existing A.J.S. customers. As a result, Diamond Motors purchased the A.J.S. sidecar business, together with the 'Graiseley' trade mark for £475, and continued to produce 'Graiseley' sidecars for ex-A.J.S. customers, including Swallow.

In 1935 the business moved to the old Villiers foundry building in Upper Villiers Street, Wolverhampton, and extended the product range to include the 'Graiseley' pedestrian controlled electric truck. It initially proved popular as a cheap milk delivery vehicle, but then found uses in hospitals, factories, and warehouses, where its fumeless, noiseless, and economical operation, made it an ideal form of transport.
