What is it?

[boB]

I would have to guess it is some kind of impedance measuring instrument.

Maybe a Wheatstone bridge ?

Looks kind of like an oscillator board with the 2 tubes on it ?

But what is that copper tube on right side,   to a pressure Guage.....and another copper tube on left side panel...oh the mystery!

Oh yeah... that !   I saw that and just "assumed" that it "might" be a method of connecting
the UUT (Unit Under Test)...  But I can't really tell if it is connected to anything or not besides
coming into and out of the front of the box.

With that compression connector I gotta bet that is a pressure Guage ......but with the tubes and tuning coil?  no pressure transducer?  This one is a stumper!

Have to give this one to boB!  His "measuring instrument" and "UUT" unit under test comments/guess's are both right in the ballpark so I gotta give it up! This "instrument" was used for measuring and tuning/diagnostics of automobile/truck engines way back when.

I was going to originally guess a Gonculator.  http://www.urbandictionary.com/define.php?term=gonculator

I would never have guessed the REAL product this was but sort of close I guess.

Why does it look like high frequency stuff though ?  What exactly does this
unit do ?

Looks cool !

I think that is probably an oscillator to produce AC to test the condenser (capicator) across the points.

And probably also feeds the white coil at the bottom for the spark plug tester.

Not a charge controller! But then it all depends on how you look at it.....

I really like that guess !

I was going to say it was a speaker but sure looks like a very weird one if it were a speaker...

And too many mounting holes around the perimeter.

This should be a fun one. A clue: Some type of "Record" is involved.

boB, please check your PM's. Note: PM is unrelated to this thread.

I am going to guess that it is a rocket engine.

Bingo!!!

Extra credit if you can determine "what rocket engine" ? Remember, a "record" is involved.
