Nose gun installation. Note the former serial number “366”.
The two forward rows of seats were removed to allow the installation of additional fuel tanks.
Cockpit of the 247-Y had the addition of the gun charging handles seen jutting from the instrument panel in front of the pilot’s yoke.
A one of a kind aircraft if there ever was one. When this Boeing 247 began life with United Airlines, I doubt many believed it would end up being converted into a warplane but that is exactly what Boeing itself did. NC 13366 earned money for United until they retired the 247. Boeing then reacquired the aircraft in order to fulfill a rather unusual request to turn it into a militarized airliner for China. This Boeing obviously did.
