P-A-G Shelled Corn Yield Computor

This little 4-inch wheel converts pounds of shelled corn to bushels. I don't know how moisture content is figured.

There is no date on this one. It's in decent shape, being made of a sturdy, coated cardboard. Pfister Associated Growers may or may not still be around. The record in their home state seems to indicate it's dead. Poor Pfister.
