I could not resist this one Ebay. It is a so-called "Pintsch Regler" or carbon pile regulator from a Wuerzburg radar. It stabilizes the supply voltage for the various equipment modules of the Wuerzburg radar.
It operates by varying the pressure on a stack of carbon rings. The changing pressure changes the resistance of the stack which changes the output voltage. The pressure is changed by a large variety of a voltmeter instrument which is connected to the carbon stack with a system of cogs and levers. when the voltmeter turns under influence of the output voltage the pressure on the pile changes regulating the output voltage back to it's setpoint.

You can clearly see the carbon pile on top and the coil of the "Voltmeter" in the bottom

In the bottom of the chassis you can see a number of red selenium rectifiers, these rectify the output voltage for the "Voltmeter"

The Manufacturing code is eao. This stands for "Pintsch K.-G" in Berlin. It is 1942 dated.
