My Uncle Alan, now passed, did his national service in the RAF shortly after the war. He worked as ground crew on Mosquitoes, he had a picture of himself standing in front of a Mozzy with a large glass (or presumably some kind of Perspex) nose.
He was in my garage one day and noticed one of those small box spanners on the wall with a couple of universal joints in the stem (much beloved of Reliant mechanics) and I remember him saying he'd have given his left arm for a tool like that when he was working on the Mozzy.
