Default I've got a whatsit.

I asked the flea market dude what it was and he replied, $10 dollars.

The circular object in the last photo is an old D cell negative end.

If you click on the photos they expand.

At some point in time Brown Instrument Company was a division of Honeywell that made process control instruments. I have seen their name on something but I cannot remember what it was (it might have been a circular chart recorder).
I would have to imagine it is some type of calibrator/simulator.

What are the markings around on the dials . If they are letters J K T E then it would be a thermocouple calibrator .

I'd vote for a simulator, as I don't think a thermocouple is calibratable..

Back in the day I became instrument foreman in a large cellophane plant. We had hundreds of Brown Instruments. The ones I remember most were the steam flowmeters. They had a number of rods that hung at various depths in a pool of mercury.
These flowmeters had two impluse lines one upstream and one downstream of an orifice plate.
As flow increased, the mercury would rise, shorting out the higher rods. The greater the number of rods.
The meters worked fairly well but if one was not careful, during maintenance, the meters could spit about 10 lbs of mercury into the steam.

I replaced all of the mercury meters, during my tenure.

No markings on the settings sorry.
My first guess was a decade box for ohms or farads then there is the battery.


There is no meter per-se and the front cover is translucent enough to see 20 ga. copper wires without insulation free air just below the cover. You can bump the box and see them vibrate like a filament in a bulb. The wires are straight and bent into right angles as if manufactured exactly like the schematic was drawn. Those wires were attached to the metal settings around the dial.

Except for the cover the entire box is wood.
