Reliable Egg Scale - 2nd generation  Brass nameplate, black base

This scale was tested for 20 and 23 ounces per dozen chicken eggs, while earlier models were tested for 19 and 22 oz. per dozen. The range was between 16 and 29 ounces per dozen.

The scale could grade a variety of sizes through a combination of a flip weight on the beam and loose weights that hung on a notch in the beam or sat on the egg holder. This is a second-generation Reliable Egg Scale.

It was made of non-magnetic pot metal and sat on a non-galvanized tin base which was notched to fit on an egg case. A brass-colored nameplate was attached to the end of the base opposite the egg cradle. 

The directions for operating the egg scale were printed on a card and slipped underneath the base of the scale. The city postal code on the directions indicates that these were made between 1943 and 1949 when the company was sold. This generation of scales sold for $3.45.
