This thread prompted me to go rummaging in my various boxes and tins of old stuff. What do you know, I found a battered old original badge, the atomkraft version. Can’t remember where I got it. I was never a protester at the time, and I went to work with pwr and agcr as a naval engineer officer. Yes memory gets tricky, but I recollect an old girlfriend (Marie?), it was over 50years ago) who was into all that. Perhaps it came to me that way. Should I put it on eBay and make a killing?
