SCARCE cast iron DEERING tractor seat made in CHICAGO ILL USA

WHAT A FIND! We have a DEERING cast iron tractor seat! Not sure of the date of it, or what it went on, but there is a D256 at top of seat...This is original condition with no new paint or cleaning...Im sure some liquid gold, or whatever you cast iron collectors use would have this puppy shiny like old Glory! Seat measures about 19 inches across and about 15 from front to back...I did a TON of research and I could not find this particular one...EXCELLENT piece for any collection! If you have any questions feel free to ask...I have shipped old cast before, and I know it requires extra special attention...If you plan on bidding, GOOD LUKC!
