Austro-Daimler engines were built originally in Austria from the designs of Ferdinand Porsche, and later produced in Scotland by Arrol Johnston and William Beardmore and Son. Austro-Daimler was among the first to produce aircraft engines that attained a marked degree of success. The British, Russian, Italian, Austrian, and German armies adopted Austro-Daimler engines for airplanes and dirigibles prior to World War I, and airplanes equipped with Austro-Daimler engines set many early records.
Austro-Daimler almost exclusively made vertical four- and six-cylinder inline engines; and this Type D-35 was the only V-12 they ever made. A very rare artifact, this engine is believed to have been removed from the Ungarische Flugzeugwerke A.G. K 405 flying boat (a Hungarian license-built Brandenburg W 13) by the Naval Aircraft Factory in 1920.
