BURRELL 4-INCH SCALE SINGLE CYLINDER AGRICULTURAL STEAM TRACTION ENGINE. Built from kit supplied by Steam Traction World in August 2021 and recently completed by builder/vendor Eric Marsh. This is my second Burrell build (previous was Burrell 2-inch), and follows considerable experience constructing six light aircraft over many years. For sale, fully steamed and snagged, and with a restricted guarantee, for £20,000.
