The story
After World War One the Chemische Fabrik Orloff Hansen, which had previously manufactured munitions, changed to small car manufacturing under the amended company name Pilotmotorenwerke Bannewitz. Walter Wippermann managed the company. Its first car called the Pilot was the 6/22PS. The 1500 cc engine was the first German 16-valve four-cylinder engine in series production.
