Picture 258 in Hackenberger shows the single
Sánchez-Besa floatplane bought by the Austro-hungarian marine, where it came in as
Seeflugzeug No.14. The machine was not succesfull and flew very little (remarkable that it was photographed during a flight).
The machine can be distinguished by its very long central float protuding far before the nacelle. Also characteristic is the pointed nose )see drawings) and the Voisin-like rudder. This Sánchez-Besa floatplane is sometimes given as a floatplane version of the Voisin "L". The divide between Voisin and Sánchez-Besa was very shadowy as SB was also the sales man of Voisin for a time.
The machine had a 100 hp Gnôme rotary engine as a pusher. The machine was ordered in March 1913 and delivered on July 14, 1913.
