Looking for leads on early horse-drawn grader?

This unique, early horse- or mule-drawn grader has been loaned to the Eastern Washington Agricultural Museum. The one-piece circular blade can be positioned (using two levers) to move material left or right or carry it straight ahead. The two levers are cast with the name J.D. Adams, Indianapolis, Ind. We’d like to learn more about this unit. Anyone with information is asked to contact me.

Thanks!
