Kees Smulders sent these very clear pictures from a Canadian made luminous disk in his own collection. He bought it 30 years ago at an army surplus store in Arnhem. It’s a Canadian disk, marked R.L.I. 1942 (RLI stands for Radium Industries Limited). It is still complete with its brown nubuck leather pouch with a brass press stud, and a tie down cord. I had never seen one like this in such good condition and with a pouch.
