It would be awfully nice if he were to draw what’s on the original drawings – stuff like dimensions and/or steel shape and weight -- instead of assuming everything was going to be used exactly as he made models – sheet of paper with un-dimensioned drawing at HO scale where one lays out styrene of the approximate size – or oversize -- for gluing.  As they were done all of his drawings – and most in MM from others -- are without value to me and in all likelihood w/o value for anyone trying to make something at Shapeways.
