Bird Thruline 100uA remote meter model number 4712. It's ex RAF and is complete with a 2.9 metre cable and Bird DC Connector
The case has some marks consistent with use. It does have documentation confirming it's serviceable however I am unable to test electrically .
The meter is scaled for 5, 10 and 25Kw and the heavy machined case measures approx 145mm by 165mm by 85mm deep.
