I agree that the truck looks like an Opel Blitz! I know some were used by Civil Defence etc. during the war being requisitioned civilian trucks. All were imported by General Motors Limited but regrettably the Southampton Plant never did assemble any...Chevrolets (cars and trucks), possibly Pontiacs, and then in 1940 Ford & Chevrolet CMPs, Ford & Chevrolet sedans and trailers.
