<b>261. SIKORSKY AIRCRAFT ARCHIVE </b>IGOR SIKORSKY (1889 - 1972) American aeronautical engineer and inventor of the first helicopter and multi-engine plane. A large, impressive historic archive of photographs and documents documenting early tests of Sikorsky's helicopters and flying boats from 1925 to 1945. Included are approximately 200 original photographs of early Sikorsky aircraft, including biplanes, helicopters and seaplanes, with many close-up shots and images of various aircraft following a crash. Among the aircraft represented is the first helicopter, the VS-300, VS-457, the first mass-produced helicopter, the R-4, the S-43 flying boat, and various other aircraft, original drawings and calculations, many sketches and schematic drawings of various machinery, test results, and so on, some of which appears to be in Sikorsky's hand, and a descriptive specification of the S-43 flying boat. Also included is an original blueprint carbon signed by Sikorsky showing an inboard profile of his VS-327 helicopter (later called the R-5), dated March, 1942 and an account of the first R-4 delivery flight made in June, 1942. A most informative and important archive, in overall fine condition.<b>$500-600</b>
