Computing Scale


This computing scale has a green finish and circular glass plate. A fan-shaped scale displays the weight (from 0 to 10 lbs.) on one side and the cost on the other. Raised letters (front and back) read “National / Store Specialty / LANCASTER, PA.”

Organized in Bareville (Lancaster County), Pa., in 1908, the National Store Specialty Company produced the Pennsylvania Gas Pump (between 1914 and 1935) as well as the Pennsylvania Computing Scales. It is now the Pennsylvania Scale Co.
