The Albatros D.XII was a German single-seat fighter biplane first flown in March 1918. It was the last of the Albatros fighters completed and flown before the end of World War I and had the same slab-sided fuselage seen on the Albatros D.X.
The Les Mureaux 3 C.2 and Les Mureaux 4 C.2 were French two seat, parasol winged fighters, flown in 1927-8, which differed only in their engines. They were developed into near identical army co-operation types, the ANF Les Mureaux 130 A.2 and ANF Les Mureaux 131 A.2, in 1929-31.
