Air Sampling Pump and Sampling Cylinders

Air Sampling Pump and Sampling Cylinders.
Made from steel, brass and rubber. Size pump 14″ inches (closed), 20″ inches (extended). Cylinders 9″ x 1″ inches.

The air sampling pump was used to take air-samples for testing. The cylinders would push and screw into the pump on a bayonet style fitting and the pump would work like a bicycle pump action (push in and pull out, with a one way valve, pull air into the pump chamber and push that air into the cylinder under pressure).
