This Martin MB-2 is actually about 1/74 scale. This is the 1988 issue. The Martin MB-2 was the first U.S.-designed bomber produced in large numbers. First ordered in June 1920, it replaced the handful of British Handley-Page O-400 and Italian Caproni bombers produced in the United States under license during World War I.
While the Glenn L. Martin Co. designed the aircraft, it built only the first 20 MB-2s. The Army Air Service changed the Martin designation to NBS-1 for Night Bomber Short range. The MB-2 became the Air Service's primary multi-engine bomber until replaced by the Keystone bombers of the late 1920s.
