This is the "birth certificate" for the 1939 John Deere "A". Phil always keeps the tractor's genealogy, if it's available. John Deere is the only manufacturer that kept these kind of records, but it allows you to find out when the tractor was completed, where it was "born", when and where it was shipped, and what kind of special equipment it had when it left the warehouse. Usually, each tractor was built to the specifications of the buyer. Of course, as the years went by, things were removed or added. but this allows a person doing the restoration to equip the tractor EXACTLY the way it was when it was originally manufactured. NEAT, huh?
