Ecuadorian–Peruvian War
Peru ordered ten Model 8A-3Ps, these being delivered from 1938 onwards. These aircraft were used in combat by Peru in the Ecuadorian–Peruvian War of July 1941. The survivors of these aircraft were supplemented by 13 Model 8A-5s from Norway (see below), delivered via the United States in 1943 (designated A-33). These remained in service until 1958.
