Take a look at this amazing world war two compass they were used in RAF (formerly known as Air Ministry) airplanes - just imagine it could have been in a Spitfire or Hurricane - with fluid inside and undamaged glass and in the original carry box this is a wonderful piece of militaria for the collector or a great display piece with its gun metal grey covering
