One wooden thresher roller with wooden pegs to grind and metal rings at end of thresher.
If this thresher is H.7200.269, then it was donated by Bob Parsons on 6/27/1960...but this information is only valid if this item is actually H.7200.269.
Potentially from the Roy Crane Ranch in Stonewall, Colorado if this FIC ends up actually being H.7200.269.
