I had a 32 ? Willis with a Sheve Valve engine and although the scrap iron dealer was paying 3 cents a pound for iron he would only give me 2 cents a pound for a Willis Overland Knight with a shelve valve engine. You should actually have one and the owners manual and you can stop talking through your imagination.
