Tractor Scouting » DW-1109-ANTQ-SB1a
First, do the research. Have a clear idea of the tractor you are looking for by using one of the many tractor books available. The more-detailed ones are make-specific and have serial number information. You wouldn’t have known how superb this 1957 450D was until you looked it up in Fay and Kraushaar’s equally superb “Hundred Series Farmall” book.
