While Golden West Airlines leased an early SD-330 from Short Brothers for a couple of months in 1977, the airline owned and operated four others. These were acquired by the US Army after the carrier ceased flying and the aircraft were stored at Moline IL in 1984. N331GW was delivered in August 1977 to become C-23 Sherpa 85-25343 with the Army. Retired in 1992, it was stored at Naval Air Engineering Station (NAES) Lakehurst, New Jersey. The aircraft moved to the Millville Army Airfield Museum circa 1998.
