The Bücker Bü 181 Bestmann was a trainer developed in Germany on the brink of WWII. It was widely used by the Germans but also by a large variety of Air Forces around the world. Sweden ordered 120 Bestmanns in 1942 to make a dire needed replacement of older trainers. These were licensed to be constructed by Hägglund & söner in Örnsköldsvik, Sweden.
Here are pictures of two Swedish Bücker Bü 181B-1 Bestmann, one at Västerås Flygmuseum, Västerås, Sweden and one at Frlyvapenmuseet, Linköping, Sweden.
