Potez 25TOE
Originally designed for a different type of engine, the Hellenic Po 25 A2 was a 2-seater army cooperation/observation airplane.
Twenty four were purchased in 1931 from France, and 500hp Hispano-Suiza engines from the Air Force warehouses were installed on them. The engines were originally intended to be installed on the Bre XIX, but this did not happen due to large cost. The Po 25 was designed to bear different types of engines, but not the specific H.S model that was installed. The fitting was combined with the placement of a 25kg balast in the tail, which according to the opponents of this choice caused many accidents.
It is mentioned that in 1940, only 17 Po 25 A2 were left. It was used in the early stages of WWII, as it was too old. From the construction company it was given the name "Greek Plane", as it is referred to the airplane's technical notes, published specifically for Hellas.
Note that the only reference found the aircraft seem to have wire wheels (includes "Σ14" with other 2 in formation), but is possible some where fitted with fixed wheels or these came with spares.
