RAF chartboard, type B, 1940 dated


Code: M25330

R.A.F. Bigsworth Chart Board, Type 'B', MK.2.  Stores reference 6B/137.  Wooden plotting board approximately 43.5 x 43.5cm fitted with a hinged articulated brass plotting arm and adjustable perspex rules.  Marked to reverse with Air Ministry King's crown stamps and 1940 date code.  The board has quite deep scratches, scuffs, marks and wear but is in good overall condition.  The plotting arm is also very good useable/working condition although the rule doesn't lie completely flat to the surface.  The board retains the often missing canvas pen pocket but lacks the elasticated hanging loop.  These chartboards were used by aircrew navigators and used to plot routes during flight.  A lovely display item.  Stock code M25330.
