These are circa 1900 examples of egg scales made by the Reliable Manufacturing Company, Los Angeles, California. They have been tested for weighing eggs between 19 and 22 oz.
 
The minimum weight for a medium egg was 1-7/12 oz (19 oz per dozen) and for a large egg was 1-5/6 oz (22 oz per dozen).

Note: Modern USA egg sizes are 1-3/4 oz
for a medium egg and 2 oz for a large egg.

"Speed, accuracy and endurance are built into every feature of this scale. The shift weight can be reversed to weight [sic] pullets or extras merely by the flip of a finger. Steel bearings, finely grounds [sic] to a knife edge, eliminate friction and insure [sic] rapid operation. Notched board base fits across top of egg case to facilitate packing."

The original cost of the scale was $2.90.
