This all original and working brass front spring balance scale has advertising on it that reads, ‘Cow Chow – Makes More Milk at Less Cost – Don’t Guess use this Purina Milk Scale’. This is a spring balance scale that will weigh up to 30 pounds. Notice the checkerboard design on the front of this scale that reminds one of Purina advertising items. This scale measures 16 1/2″ long front the top to bottom hooks and is 4 1/2″ wide.
