Hi,
Found this NOS US Gauge Co. manifold pressure gauge. 2" in Dia. PN: AW-2-3182, MS280018-1
Mfg Date is 6-25-69

Anyone know what aircraft system this was used on?

Just for fun.

Just a guess. The Manifold Pressure on the propulsion system. ;-)

There was one on one of my Taylorcrafts when I got her. Interesting in that I had a fixed pitch prop and a Stromberg Carb. I had an instructor I knew tell me I needed to leave it hooked up since I could get my Barometric Pressure from it in flight if I didn't have weather reports available. I decided maybe he wasn't a good instructor for me. In fact, I never even flew with him again after that.... in anything.
