WWII-era hand bearing compass, Type O.6.A., in its original wooden case, as used in aircraft of the British RAF Coastal Command.
The 06.A. is hand-held compass, used by an observer (hence the "O" designation. Reference numbers for pilot compasses began with "P") to take navigational bearings in situations where a fixed compass could not be used, or to determine correction factors for fixed compasses. The handle holds batteries (not included) to power an internal lamp, which would internally illuminate the bowl of the compass. With the bearing target sighted through the "V" atop the glass prism, the observer would read the direction of the bearing through the prism mirror as it is reflected up from the compass card. The markings on the compass card are reversed so that they appear correctly in the prism mirror. A stamp inside the box says "Examined 9 Nov 1944, Glasgow"
The compass measures 9.5cm in diameter and 19cm inches long. The case measures 13 x 13cm and 27cm tall. The compass card rotates as it should. The mirror in the prism is slightly distorted, but the card can still be read through it. The rubber cushion inside of the case has deteriorated and softened.
