New Winona grist mill | Smokstak® Antique Engine Community
Apr 09, 2015· I have a no. 2 which is rated for 2 to 4 and they made them to use from 1/2 to 10 I believe they were made by New Winona but have no definitive proof. They also have a quick release lever to open the burrs and the thrust bearing is oiled by a chain that dips into the oil reservoir.
