I know the guy that made the 36 JD "A" & the Farmall, all made from scratch! Welded up pieces & machined, for one of them he did find a carburetor that fit. He said the hardest part on the "A" was the tapered axle housings, since they aren't a straight taper. And, yes, they both start & run!Great pics Lowell. Thanks for sharing them. :hi: I really like the scale tractors and wonder how they were made.
