1930s technology in an air/fuel meter

This arrived today. It is rough. I have a friend who may be able to get it functional. If not the meter will make good shop art. The main principal of operation is a Wheatstone Bridge. Studied it once a long time ago when we had an old oxygen analyzer and had to know how they worked. The meter is about 16 in. X 6 X 5 in.

That is WAY COOL!! I love it. I sure hope you can make it work. It might be slightly impractical set on the dash of your car but it sure isn't impractical to own!!

I have 3 similar exhaust analyzers. I use them to get in the ball park but still fine tune by reading the two front plugs on stock intake manifolds. G.M.

G.M. Do you have any pointers on servicing the bridge?
