Lot of four unsigned war-date ‘Combats in the Air’, combat reports, each 1p., varying sizes all dated 1917 from various flying aces, including RAYMOND COLLISHAW, FREDERICK SOWREY, GERALD MAXWELL, and FRANK QUIGLEY. The pilots detail attacks on enemy planes and give the results of those attacks, most being successful. Quigley’s report is the most intriguing as he describes dropping four bombs on the Rumbeke Aerodome before engaging in a few skirmishes with the enemy. File holes and chipping, overall very good. Sold with a rare war-date cut signature from MAJOR C. H. BUTLER, British RFC commander of 209 Squadron to which Roy Brown was attached. Major Butler sortied with Roy Brown on von Richthofen’s last day, but their two groups became separated before the famous dogfight.
