RAF Mk.IV binoculars, cased


Code: M25475

'Binoculars, Prismatic, 5 x 40 MK.IV,'.  Stores reference 6E/383.  Manufacturered by Ross under R.A.F. contract.  Introduced in 1941 these substantial 5 x 40 fixed focus binoculars have coated lenses and large single piece black rubber eye shield helping maintain night vision.  The relatively large diameter of the objective lens (40mm) allowed increased levels of light to pass through.  Although primarily designed for night use, this instrument was also suitable for the identification of objects at long range and reconnaisance duties by day.  This made them suitable for use by nightfighter and Coastal Command crews for spotting aircraft, shipping and U-boats as well as personnel in airbase control towers.  These show light to moderate use and wear with some rubbing on exposed areas of the casings, which are marked with War Department arrow and Air Ministry reference code.   The rubber eyeshield remains flexible but there is surface crazing and minor loss on the centre top edge.  Good optics providing a clear and crisp image.   Complete with olive drab webbing neckstrap and original grey fibreboard case.  This shows wear and use but is in reasonably good used condition.   Stock code M23457.
