Re: GEC Selectest Super 50 Mk2 fifty year MOT
I have attached a photo of my Selectest which was the subject of the accuracy tests above. The case is sound with no cracks but at sometime it developed the small blotches you can see. I can't recall when they appeared but it was a long time ago. They don't come off with safe cleaning agents. By the way, has anyone got a pdf copy of the manual they could send me?
