This is an injection-plastic aircraft model kit.
From the manufacturer:
The Nakajima B5N1 "Kate" was the most numerous Japanese torpedo bomber of the Second World War, and while primarily operated as a torpedo bomber from carriers, it also saw service as a land-based bomber. A single-engine monoplane, it was defended by just one rearward-firing machine gun, operated by the radio operator, and its relatively low speed left it vulnerable to enemy aircraft. However, it proved to be a devastatingly effective machine in skies not defended by enemy fighters, performing well at Pearl Harbor and going on to have success at the Battle of the Coral Sea and Midway.
14.2cm long and 21.6cm wide when completed, with 105 parts. Includes decals for two marking options.
