The first company called Bayerische Flugzeugwerke (BFW) existed until 1922 and became BMW. The second BFW was a continuation of Udet Flugzeugbau, and became Messserschmitt. Its first new product was the sole BFW 1 Sperber, a development of the wooden Udet U-12 Flamingo with a steel tube fuselage frame and N-type struts. It first flew in the autumn of 1927 and was sold to aerobatic pilot Alexander von Bismarck in February 1928. From 1929 it was owned by another aristocratic aerobatic pilot, Prince Eugen of Schaumburg-Lippe, and also flown by Oskar Dimphel.
