Universal Chemists Chekometer - Vintage Wall Hanging Vacuum Gauge - Service Station
 

This is a wall mounted vacuum gauge which I believe dates to the the pre war era. It appears to have been manufactured by Universal Chemist company. It was hanging on the wall of a local shop for 50+ years and still works. It is large (about 2 feet wide), I will have to take exact measurements Neat piece of memorabilia, I haven't seen another. If interested I can send more detailed pictures. 400+s/h
