The " Talleres" (or workshops) of the Escuela de Aviación Militar,( EMA). at El Palomar built small series of Henri Farmans and Bleriot X-II. A French immigrant, Paul Caistabert began to produce a series of aircraft in 1910, the first to fly successfully was the Caistabert II, completed in 1912, the Caistabert III, operated by the EMA), the Caistabert IV, four of which alongside a model V were exported Uruguay and employed by that country's Escuela Militar de Aeronáutica,. Single examples of the Caistaber models VI and VII were completed during 1915.All of these were monoplanes, similar in appearance to the Bleriot,although an original design. In the fourth photograph from the left, opposite a number of Ansando SVAs acquired postwar, you can see a gaggle of Caistabert IVs.
