The Beau served as a heavy fighter and night fighter, but is perhaps best known for its ‘Torbeau’ TF mark that saw great success in South East Asia. #ww2 #wwii #beaufighter #bristol #warbirds | Daniel J Wheatcroft | Facebook

Bristol Hercules, two-row 14-cylinder sleeve valve radial engine, designed by Sir Roy Fedden at The Royal Air Force Museum London. While not as famous as the Rolls-Royce Merlin, the Hercules powered over a dozen types, including the Short Stirling, HP Halifax, Vickers Wellington and the Bristol Beaufighter. #ww2 #bristol #hercules #warbirds #wwii | Daniel J Wheatcroft
