The Curtiss-Wright CW-19 was a civil utility aircraft designed in the United States in the mid-1930s and built in small quantities in a number of variants including the CW-23 military trainer prototype.
While the design was never perfected for the civil market it was originally intended for, a militarized version was soon developed that replaced the side-by-side cabin with tandem seating and added provision for guns and bombs.
The second aircraft built was a CW-19W, which featured a much more powerful 145 hp Warner Super Scarab in place of the Lambert engine.
A variety of armament options were also available, including a synchronized fuselage-mounted machine gun firing through the propeller arc, two gun pods mounted outboard of the landing gear, a flexible mount for the second aviator to use as a defensive turret, bombs, and an auxiliary fuel tank.
In this form, designated CW-23, the aircraft was offered once again to the USAAC, this time as an advanced trainer, but once again the service was not interested.
Two CW-19R survive intact, one in the Airforce Museum in Dominican Republic, and one flying with Kermit Weeks' Fantasy of Flight.
The elevation where it was on display over the monument of the Bolivian War Hero in La Paz Bolivia kept it in pristine condition at an altitude of over 12,000 feet the corrosion was very minimal.
