Hi guys, Just wondering when "Plastic Explosive" began to appear in stores at OBs, as the Diaries seem to be saying that early on, Plastic wasn't immediateley available due to shortages, and the gelignite issued was their main explosive, together with blasting gelatin's, in either Du Pont or N.S. Polar ???, also, was N.S. Polar Gelignite from Canada ??, or was it a Nobel Explosive ??. Kev.
