Mercedes-Benz Bakelite Tire Pressure Gauge office If you are as interestedPeriod German tire pressure gauge from Mercedes in Bakelite. Possibly post war made, but this style was introduced in the 1930's and continued in production into the post war years. It does not work as far as I can tell. It does hold pressure when you put it on a tire but I did not notice any reading.
