He kits some 15 size warbirds that are exactly what you describe. They aren't cheap, but the quality is astonishing. I have one of his P-40s and it its great! The are reproductions of some old Midwest kits with all the bugs and errors removed. I want to do my P-40 in the colors of the Aleutian(sp?) Island P-40s of WWII.
