The sole Grouse fighter at the ILUG aeronautical exhibition in Gothenburg. It was sold to Sweden but this was only after it had been modified to a two-seat trainer in 1925. The construction number was apparently changed then from 1 to 2. Photo from: Museum of Gothenburg

Tracing it origins back to the British Nieuport Nighthawk fighter, the Grouse sesquiplane led to the Grebe fighter. The sole Grouse, G-EAYN, was converted to a two-seat trainer and sold to Sweden in December 1925 where it was designated Ö3 as an 'exercise' (advanced trainer) type aircraft. It was withdrawn from use in 1929. Photo by: Karl Johan Stenhardt / Östergötlands Museum
