Ohaus 4-Pound Grain Scale

This Ohaus 4-pound grain scale is used to determine the weight of a bushel of grain. It has a “Two Quart Dry” bucket, which means it is a Winchester¹ bushel measure (Imperial bushels do not distinguish between liquid and dry measures).

It can also determine the percent of moisture and/or inert material in a sample. There are three weight measures on the beam. The top is the weight per bushel, the middle is the weight of the sample, the bottom line is the percent of deduction after cleaning and drying.

This example is labeled simply as “Ohaus.” National Scale Works (NSW) used the Ohaus brand, and then the company became OHAUS Corporation in 1947, dropping the NSW name. So, was this example made before or after the 1947 corporate change?

The scale is made of aluminum with iron pivots.
