Smile Re: Series 2 Megger insulation and continunity tester

Good evening,
As requested here is a picture of the meters calibration, test and inspection card. It is held in a pocket under the scaleplate with a small flat spring. Final inspection 20 January 1958. A nice little bit of history there. I will have to see if my others have got a calibration card.
