Radio Gages?

[Thälmannpionier]

Hello
i have 3 gages here..probably from a radio.
could someone please tell me where they were fitted in?
Or are these more generic and used in any kind of WH/LW/KM Radio so to say?

They will be for specific equipment, but I can not tell you exactly which. They are not from commonly used types, I checked.The Voltmeter on the bottom is for a battery operated piece of equipment using 2V filament voltage and 150V anode voltage, but it is not from a Torn.Fu. Perhaps they are from calibration or test equipment.
