For sale is a WW2 British Army RAF Air Ministry Map Plotting Tool Alidade R.E-Co MKII, which is also marked with a broad arrow. This dates to the early 1940s and is made from solid brass which has been painted black.
An alidade or a turning board is a device that allows one to sight a distant object and use the line of sight to perform a task. This task can be, for example, to triangulate a scale map on site using a plane table drawing of intersecting lines in the direction of the object from two or more points or to measure the angle and horizontal distance to the object from some reference point's polar measurement. Angles measured can be horizontal, vertical or in any chosen plane.
This piece is in good condition.
This will be sent via Royal Mail 1st class signed for and dispatched within two working days. This would make an excellent Christmas present for a wartime British army field gear collector. Also happy to send internationally.
