Georg will always be known to as the Electrician from 3 Plant and along with the late Mike Stenson helped moderate this forum in it's early and more busy days.
I too recall the odd Skype session with Georg, one in particular was when the late Frau Anita Reschke was visiting at my house in Omund and Georg called, the two of them sat there talking about the past in the German narrative.
Georg had a wealth of knowledge about the mining area and in particular the 3 plant commissioning.......
To the entire Ruf family, my sincere condolences on his passing,
