These are Standard Light Utility Vehicles which are part of the Airfix WWII RAF Bomber Re-Supply Set.  One is included in each box, it is essentially a light truck and a quick build in 1/72 scale.  Many of the kit parts are molded on the clear sprue, but mine suffered from the dreaded Airfix flow lines so I cut the portions representing glass off and replaced the windshields with acetate.  There were also gaps at the sides where the cab joins the hood which I filled with Perfect Plastic Putty.  Other than that they build up nicely.
