Wensleydale.....re post 335.....the spilt paint at RAF Finningley. I met the bloke who claimed to have knocked over the tin. MAEOp Murgatroyd. He was in his 50s at RAF Leeming in about 1990 having finally left the kipper fleet when I knew him and he described being a young recruit learning his craft and being told that prior to the forthcoming AOC's Inspection he and his mates were to paint kerb stones. The way the military do. Once the tin was over what else could they do but make it 'official' by making a nice square.
Now I can't be certain about the truth of Derek's tale but I do know for a fact that the square was still there in 1981 when as a student Nav I had to paint it again, just prior to an AOC's Inspection. It was on some innocuous bit of road in the middle of the Station and had obviously been re painted many times before I got to it.
