Well between them Lawrence and Al have it. If I told you it came from the company I work for in the most recent clear out and that the company is in the consumer electronics field (that was to have been the next clue) and at one point designed TVs. The one thing I didn't show was the connector on the end of the red cable - a connector for the EHT connection to a CRT. That would have been a bit of a giveaway.
So it's a meter for measuring the EHT current of a CRT. Well insulated to cope with 25kV or more and the 2mA FSD allows it to be used with colour CRTs. The socket is to accept the EHT connector of the TV with the EHT cable/connector connecting to the final anode of the CRT. The two loops are across the 68ohm resistor, I assume to act as a spark gap if the resistor fails.
So Lawrence and Al have the satisfaction of deducing the correct answer.
Well done
