Zimmerman first made sandstone mills in 1895, which are not included here - we are looking for photos or existing sandstone mills - both in wood frame and metal frame. That being said, the first mills were the No. 1 & 2 with A.M. Zimmerman cast into the plate covers.

The No. 1 evolved into the No. 10 and the No. 2 into the No 12.
