Brian 48 Nav,
The bloke on the left, next to young Dougie M, is the GE. I know that because he has an extremely large lump in the top left pocket, that will be his wallet, and secondly, he was my boss when I was a GE. Curiously, it has taken until the appearance of this photograph, and this thread to realise that he actually once did the job himself. Respect.
