By Levers Optical Co. Ltd. Stores reference 22c/111. The first of the MK.IV series goggles. Manufactured with a black painted pressed brass frame incorporating hinged lens holders. Unique to the Mk.IV, the lenses fit directly into the goggle frames without the need for sub-frames around them. The goggle frame is in very good '+' condition with little loss or rubbing. The leather nose-piece is interesting in that it appears to have been made larger than usual or possibly altered. Unfortunately all of the rubber pads have perished and gone hard as usual but all strap components are excellent, the leather section having manufacturer, Air Ministry and reference marks. The clear glass lenses have some delamination marks but display well. Overall, a 'very good '+' used set of goggles. The Mk.IV is considerably rarer than the MK.IVB and this is reflected in the price. Ideal for a Battle of Britain display. Stock code G23312.
