An interesting and rare WW2 Air Ministry navigational computer Mk III H, Ref No 6B/250, ICAN Calibration. This was used by RAF aircrew for accurate and safe navigation during flights. It is made of black Bakelite with metal dials front and back. It measures 16cm long x 13cm wide x 2.5cm deep. It has chips to the Bakelite at both ends where the pencil fits and it’s has surface marks and scratches from age and use, otherwise all in genuine vintage condition and all dials move freely. This interesting piece of RAF history would make a great addition to any military / RAF collection or ideal tv / film prop. I will post worldwide by the global shipping program, please check out the overseas postage rates.
