A parts book is a good start and a wealth of information. That said, I think that you still have lifetimes worth of research ahead of you. I have never seen the original advertising for any H Farmall, but kind of doubt that they showed more than a standardized picture of the tractor, let alone the instruments. Of the four ammeters listed, it appears that only one (A.C., no mfg no.) was used before they changed their parts numbering system. As far as the wheels go, it might depend on what month your tractor was built, and how long rubber tires continued to be an option. It would seem that even in early 1942 there could still be rubber tires available. Is there a date code cast into the hub ? On my '40 one is a 'J' and one is an 'A'. To be up front about it, my tractors are work-a-day tractors. As long as the temperature gauge accurately reports that water temperature, I am not concerned that the new gauge has a little arrow above the cold-run-hot band. My feeling is that a tractor can only be 'original' once, and that was a long time ago. After that, it is 'of the period'. Since almost no one knows for sure what equipment came with a particular tractor, it does not really matter as long as everything looks and works right. Getting it right can be the hard part. Good luck in your search. Greg
