These are the Airfix Bedford trucks which are part of their WWII RAF Bomber Re-Supply Set. You get one truck in each set but have the option of building it as either an MWC water tanker or an MWD light truck. I purchased two sets so I built one of each version. The kits are well engineered and go together without any surprises, the only down side is the clear parts had the dreaded Airfix flow lines and so the windshields were replaced with clear acetate. I modified the water tanker by lowering the equipment boxes on the sides of the tank and replacing the walkways with P.E. from Brengun.
