It doesn't appear in my log book during my time at SM (74-80), but I am sure it was there. I did less flying from 77 - 80, ( well, I was supposed to be on a ground tour, only manage 450 hours in 3 years), so perhaps it was around then.
Story I heard was that a couple of lads in the paint hangar at KS opened the first tin, called the Chief over and asked if it was the right colour. He checked the Section / Ref. No., and told them to get on with it. Seems some clerk had transposed two numbers.
