I bought an old Ford tractor.  It has plate on one side that says Dearborn Farm Equipment, Mod#14-3, serial number 1879.  On the motor, on another plate, its has *8N72038*.  It has the large six lug rear wheels, which I believe is a 9N Ford.  From this info can anyone help me identify what I have purchased?  (seller told me it was a 1940 8N, but I understand 8N's weren't built until 1947.)

Thanks!
