Wow! OK...I know something is only worth what someone will pay. I ran across an item similar to one I have sitting out in the shed. Mine is covered with paint...and a blanket. Maybe I'd be better to move it outside, and let it acquire a rust patina. http://www.ebay.com/itm/Antique-American-Industrial-Cast-Iron-Case-Steam-Tractor-Advertising-Eagle-/321060243827?pt=LH_DefaultDomain_0&hash=item4ac0ae8973
This was originally painted !! You have the same identical one with original paint ?? With CASE on it ?? The one you posted has 7 offers !! Need to see yours !! If its in original condition your payday could be better that the one you posted although I don`t think its worth quite that amount !!
