Remember the Canadian made pin-on type disk I wrote about? That was back in 2015.
Now I get a mail from Aaron who is also a collector of these disks and he bought this one. He says its very rare (it is) and the RLI pin-on badges were only used by the Norwegian paratroopers who went in to destroy the heavy water facility the Germans held so dear. Remember the TV series “The Heavy Water War“? Here you find more information about the actual history of the operation.
These badges were an order of magnitude brighter the other badges we have. This was because they ditched in the snow on skies and had to ski quite a distance, you could make out the glow from approximately 100 meters away easily! They are so hot that the Geiger counter maxes out before even getting close to it. I’m not sure you’d want to have this at home in your collection.
