Mid -1939 saw a complete revamp of Bedfords, with only the HC van continuing in production. The new range consisted of the K (30–40 cwt), MS and ML (2–3 ton), OS and OL (3–4 ton), OS/40 and OL/40 (5 ton) series, and the OB bus. Also on offer was a new 10–12 cwt van, the JC, derived from the new J Model Vauxhall car. Many of the trucks sold by Bedford between June and September 1939 were requisitioned for military use on the outbreak of World War II; many were abandoned after the retreat from Dunkirk, rendered useless to the enemy by removing the engine oil drain plug and running the engine. Because the German armed forces in 1940 were, contrary to their popular image, desperately short of motor transport, many of these captured Bedfords were repaired and pressed into service alongside Opel Blitz (also part of GM) trucks by the German armed forces – although the Bedfords mainly filled second-line roles, including civil defence.
