The salver, 14½in (37cm) in diameter, 40ozt, was gifted to Johnson on his retirement in 1962 and has an estimate of £600-800 in The Jewellery, Silver & Watches Sale.
It has a mark of Garrard & Co, London 1962 and is of ‘Chippendale’ style, the field engraved Presented to Air Vice Marshal J.E. Johnson CB CBE DSO DFC RAF by the Officers of Air Forces Middle East on the occasion of his retirement from the Royal Air Force, raised on four hoof feet, signed to the underside, 37cm in diameter, 40ozt.
Despite missing the Battle of Britain through injury, Johnson's wartime record was 34 aircraft claimed destroyed with a further seven shared destroyed, three probable destroyed, 10 damaged, and one shared, destroyed on the ground.
All of his kills were fighters including the formidable Focke-Wolf Fw190 and Messerschmitt Me 109 rather than the slower and more vulnerable bombers. His own aircraft was never shot down.
