Your comments:

• I am a retired instrument artificer these instruments were used widely up to about the year 2000 and a few later models are still in use today ,The instrument shown is for the accurate measurement and supply of millivolts, its primary use was to simulate or measure the millivoltage generated by a thermocouple for the measurement of temperature usually in the industrial environment

• This unit appears to be a Cambridge Instruments Workshop Potentiometer (with potential source), Catalogue No 44226. The 44223 version does not have the batteries in the left hand compartment. I have a circuit diagram and catalogue pictures of both models. I also own a later version Catalogue No 44228
