Guy's book is very informative, but doesn't get into too much specific detail per model, as unfortunately it appears some of the "nitty-gritty" has likely been lost to history. As Guy notes, the original "build sheets" are gone. You get conflicting information, even challenges to Guy's research. He looked at I think 30,000 documents. You absolutely need to get Guy's book and read cover to cover, as it has interlacing facts dispersed throughout. I would recommend it as your beginning point. I have been trying to piece together exactly what you are asking for for the H & M models. However, just when I think I have started to get it narrowed down, another surprise comes along. I hope to eventually create a PDF file with documentation and photos for general access by all, but it will take time. If you can find original tractors, family owned units, you get a fairly good picture of what was commonly shipped out of the factory. Talk to everyone you can find with silver or gray hair, and write it all down. If you come across something good, pls pass along. Good luck.
