This scale was made in Rochester N.Y. USA in the early 1900's by the Eastman Kodak Company.
These scales were normally used for measuring out chemicals used in photography. The image above shows a set in very good condition
(after many years use the harsh chemicals weighed make these scales prone to heavy rust). It is complete with label and weights (the smallest weight is missing).
Made from stainless steel on mahogany base it has a set of Avoirdupois weights. It was built on the Roberval principle employing upper and lower crossbeams
and edge-knife steel hinges. The old Kodak EKG logo is in the center support and a conversion table plaque (Grain, Drum, Ounces, Pound) is attached to the base.
The 6 weights are from 50 grain to 2 oz. The base is 9 inches (23cm) by 4 inches (10cm) and 1.5 inches (3cm) deep - the scales have a total height of 6 inches (15cm).
