The issue torches were crap, especially the ones designed for fighters. They were practically unusable. From about 1985, most aircrew had their own 'Maglite' torch, usually bought on visits to US Base exchanges where they were approximately a third of the price of that in the UK. The small double AAA torch was popular as it would fit in the arm pen pocket.
I still have an issue kneeboard with attached chinagraph which I use for light aircraft flying. However, I'm down to my last lead.
