Pfalz Flugzeugwerke was a World War I German aircraft manufacturer, located at the Speyer airfield in the Palatinate (German: Pfalz). They are best known for their series of Worls War I fighters, notably the Pfalz D.III and Pfalz D.XII. The company went bankrupt after the Armistice, when the French occupation forces confiscated all of the equipment, but the factory was re-used by various other companies until re-forming in 1997. Today they are a parts manufacturer referred to as PFW.
