On the evasion exercise on my CSRO cse I had found a piece of paper with an emblem of four feathers on it. Thinking it might be useful for lighting a fire I kept it. I was 'picked up' before I could use it. All of my interrogaters spent a lot of time asking what it was etc, I could honestly answer 'I can't answer that question' as I did not have a clue as to what it represented. It turned out it was headed paper for a rambling club that had wandered over Dartmoor. Evaders another one up.
