Josef Walter founded his company in Prague in 1908.  A 3-wheeled car was made at first.  After WW I a variety of vehicles was built including 6-cylinder limousines with bodywork by Sodomka.  By the 1930’s the production of aircraft engines took precedence and the last cars badged as Walter were built in 1937.
