Avro 509 / 513
Страна: Великобритания
Год: 1914

An impression by ERIC HARLIN, based on a company general-arrangement drawing, of the one-off Avro Type 509 twin-engined pusher seaplane, serial number 94, which apparently enjoyed only a brief existence in the latter half of 1914. Can readers supply any photographic evidence of its existence?
