Looking for a set of drawings for the Wall 30 cc four stroke air cooled single and or a set of drawings for the Wall two cylinder four stroke air cooled Wizard engine. I could be interested in complete engine or castings set depending on price. I have to trade the 36cc wall single two stroke, air cooled, with most castings for this engine. I could also trade some tools or equipment, what are you looking for or need? I have drivers and frame rails for Bill Moorewood's Raritan Live Steam Loco and same for the Virginia Live Steam loco. Frame rails and drivers for both are laser cut steel.
