Dumas Walnut Scale Sopwith Triplane as one of several flown by Raymond Collishaw. At the time the much-practiced Naval units got their Tripes, it was the most capable plane flying for the British and absolutely deadly to the Albatross. Black Watch squadron pilots put a big dent in their frequent Flying Circus opponents. Otherwise, it was Bloody April for the RAF. The Triplane was badly flawed in that it was almost impossible to service in the field. After only a few months of service, it was replaced by the Camel. The design so impressed the Germans that they demanded a triplane. Fokker beat the competition with the Dr.1.
