This item is an injection-plastic aircraft model kit.
From the HK Models website:
"The B-25 Mitchell was an American twin-engine medium bomber, manufactured by North American Aviation. The aircraft was named in honor of General Billy Mitchell – the pioneer of US military aviation. The B-25 Mitchell was used in every theater during World War II, and served with many other air forces after the war ended.
"The B-25 project was a descendant of the earlier XB-21 (North American-39) from the mid-1930s. The experience gained in developing the XB-21 was eventually used by North American in designing the B-25 (called the NA-40 by the company). With several modifications, one NA-40 was built to test a number of potential improvements, such as the Wright R-2600 radial engines, which become standard on the B-25."
HK Models has released a highly-detailed model kit of the North American B-25J Mitchell twin-engined medium bomber, in massive 1/32 scale! Incredible detail abounds in the cockpit and throughout the interior, as well in the Wright R-2600 radial engines, bomb bay (bombs included), and landing gear. The exterior features accurate shapes and proportions, with fine recessed panel lines and rivet detail. Control surfaces and engine cowl access panels are molded separately and can be positioned as desired. Includes decals and photo-etched metal detail parts. Wingspan measures out to 64.3cm (25.3 inches), with a length of 54.77cm (21.6 inches). This stunning kit will make a mighty addition to any collection of WWII aircraft!
