Hi
Have a friend with what I believe is a Model A "Air scales"
Looking for information on it as well as parts.
Unfortunately he is missing the internal scale and valves.

Here is a photo of the Air Scale model that is in need of some tlc

Sent a pm so that I can send you some pictures.

PM sent thanks

I have a 30+ page manual for all of this series of Air Scale meters available.

Email me if interested: jhsim@petrocollect.com
