Description: Two A.I.F. signallers use a heliograph during exercises in the Western Desert of Egypt (Libya) in Nov. 1940, during World War II. This photo was made into a A.I.F. recruiting poster in Sept. 1941. This is an official Department of Information (Australia) photo of two signallers of the 2nd Australian Imperial Force. They are using a Mance Mark V heliograph in duplex (dual-mirror) mode to signal by Morse Code using reflected sunlight modulated by tilting one mirror. This photo appeared in the Australian Sydney Morning Herald on Nov. 13, 1940 ( https://news.google.com/newspapers?id=qLVVAAAAIBAJ&sjid=spYDAAAAIBAJ&dq=department-of-information%20heliograph&pg=7317%2C1448435 ), the West Australian on Nov. 16, 1940 (http://trove.nla.gov.au/ndp/del/article/46749411), and the Examiner (Tasmania) on Nov. 20, 1940 (http://nla.gov.au/nla.news-article52389945) The poster was announced on Sept. 11, 1941, in the Courier-Mail (Brisbane, Queensland, Australia) (http://nla.gov.au/nla.news-article41941629).
