Hello, I just purchased a Ford N9 tractor and, of course, the serial number isn't visible. I'm hoping someone might help me figure out the year model. Below is a list of things I've checked to try and date it. The only thing that seems to put it on or after 1944 is that the axle radius is an oval tube (and not I-beam). Everything else seems to point to on or after 1941. Is there anything else I could check to determine the age of the tractor?
