Working Glass Dome Scientific Pump
If you are a collector of early medical objects then you already know how rare this pump is. It's made by the Janette Mfg. Co of Chicago.
I have been trading in this kind of object forever and have only seen a picture of one. It's known as the "Ticker Tape" and its easy to see why.
But regardless of its original purpose this object has a presence as an industrial art object... and it's in original working condition.
The inside of the dome is lit by it's original fixture and bulb. The dome has an impressive 14 inch diameter and sits on a solid cast iron pedestal.
Total hight is 5 foot.
