British built floatplane (Fox Floatplane) converted with Hispano-Suiza 12Ybrs engine from Fox II. Six were produced for the Peruvian Air Force to serve during the Colombia-Peru War of 1933, but by the time they had been delivered (in October 1933), the war was over. They later (with the floats removed) carried out observation duties in the Ecuadorian-Peruvian war in 1941.
