1920 Vtg Boyce Motometer Germany

Rare find from 1920. This is an external radiator temp gauge called a Motometer made in Germany by Boyce for Cadillac. The temp copy is in German which is why its rarer than most. Solid brass very heavy. These were patented in 1912 and already obsolete in 1930 when dash mounted temp gauges appeared. In german...sommer means summer. Motor zu salt means engine to cold. Enjoy! 😊👍♨️🚗🌡
