My friend inherited a pile of old electronics. Among it there is this worn amp meter. Does anybody know who produced it and where we can find more on it? There is only this "KS" logo and serial number. I cant seem to find anything about it online.

Looks like a standard ammeter movement. There should be 2 wire terminals and just put it inline at less than the max meter value. Boy, that thing is ancient and only 35mA. I'd just clean it up and put it on a shelf! The lever on the bottom front is a switch to take it in or out of the circuit.
