The Mitsubishi Ki-21, (Allied code name Sally) was a Japanese twin engine medium / heavy bomber used in the late 1930s up through the end of World War II by the Imperial Japanese Army Air Force.  The Ki-21 Sally was introduced in 1938 and by the time it was retired at the end of World War II, almost 2,100 units of all variants had been produced.  The Ki-21 Sally typically carried a crew of up to 7 airmen and had the following operational characteristics: 1) Top speed of 300 m.p.h.; 2) Combat range approaching 1,700 miles and 3) Service ceiling of just under 33,000 feet.  The Ki-21 Sally carried five 7.7 mm flexible machine guns and one 12.7 mm fixed machine gun as defensive armament, as well as, had an offensive capability of carrying up to 2,200 lbs. of bombs.  The Ki-21-11 variant, which is the subject of this model, was built in limited numbers to evaluate the aircraft's performance with more powerful engines as a heavy bomber.  This rare, older, out-of-production Mitsubishi Ki-21-II "Sally" scale model is highly detailed and includes the following features: 1) Authentic markings for multiple aircraft operated by the Imperial Japanese Army Air Force during World War II; 2) Clear plastic cockpit and fuselage glass areas; 4) Detailed cockpit; 5) Detailed radial engines; 6) Detailed landing gear; 7) Internal bomb load; 8) Molded in light gray & medium green colored plastic; 9) Movable turrets; 9) Optional position bomb-bay doors; 10) Optional position landing gear; 11) Recessed panel lines; 12) Rivet detail; 13) Rotating propellers; 14) Two different bomb sizes; 15) Paint guide in color and 16) Illustrated assembly instructions.  The box is in fair condition.  Never started and 100% complete with all parts, decals and instructions inventoried.
