I was told by a friend that you were offered a real good price for the tractor. I can"t imagine that tractor being worth that much. If you are selling,you should have sold it at the show when you got that offer. I think that was an exceptional offer that may not be matched by anyone else. Of course that is my opinion after buying,selling,trading,restoring and watching tractors sold at collectors auctions over the past 20 years. There is always an exception and that offer you got, truly was an exception.
Hope that helps.
