North
            American Aviation was formed in 1928 for the purposes of
            acquiring aviation oriented stocks and securities.
            Important acquisitions include Berliner-Joyce
            (1930) and  General Aviation (1933).  The U.S. Navy used the
            letter "J" to identify Berliner-Joyce aircraft and
            continued its use for North American aircraft.
            The acquisition of these companies marked a
            transition from earning income from stock trading and dividends to
            designing and manufacturing aircraft.  Also important was the
            acquisition of "Dutch" Kindelberger as president and
            general manager.  "Dutch" had been a Lieutenant in
            the U.S. Army Signal Corp, a draftsman for Glenn
            Martin and chief engineer for Donald
            Douglas.
            North American's second aircraft was the aircraft
            that became the AT-6 Texan, of which over
            16,000 were produced.  The Texan, B-25 Mitchell and, P-51
            Mustang assured the success of the company.
            North American Aviation merged with
            Rockwell-Standard (owner of Aero Commander)
            in 1967 to become North American Rockwell. 
            Another merger, this time with Rockwell Manufacturing, created Rockwell
            International in 1973.
            Rockwell sold it's General Aviation division to Gulfstream
            in 1980, its Sabreliner division to Sabreliner
            Corp in 1983 and the rest of it's aerospace interests to Boeing
            in 1996.
