Would anyone have a source of information on this gage:

I needed an inclined manometer and when I run across this unit I decided I would much rather have an olde quality unit like this than something new. Can't be all that complicated but Id like to use it to its best advantage for my application of measuring pressure drop across a media filter.

thanks for any feedback

Trying one more time...

Is this such an obsure instrument or aren't that many olde steam mechanics around?

Never saw one, but there is a small reference to it(with pics) in "Audels Plumbers & Steamfitters Guide #3".
If interested I`m sure you could email Dan and he would scan it for you.
