Post WW11 Scammells built a small drawbar tractor which found use in general haulage and later as a recovery vehicle. Nearly twenty of these chassis were equipped with winch and shaft/belt driven generator/switchboard set specifically for showmen. The distinctive coachbuilt body was copied by other showmen and also during preservation years.
