Both are the only flying examples in the world, The Boeing P-26A "Peashooter" and the Republic AT-12A Guardsman.
The P-26 was the firstmonoplane fighter produced for the USAAC, as well as the first modern all metal fighter to enter production.
The AT-12 was originally built as a Seversky 2PA-204A fighter bomber for a Royal Swedish Air Force export contract but were barred from delivery due to the war in Europe and so were impressed into service with the USAAF in early 1940.
Russian born Seversky changed the name of his company from the Seversky Aircraft Corporation to Republic Aviation in October 1939.
