Loire 50 was a single-engined liaison and training flying boat of the 1930s produced by Loire Aviation. Only seven were built and used by the French Navy. The 50 Bis version depicted by the pic is the prototype evolution which became the Loire 501. It wears here the nice Indian head insignia and codes of Aéronavale unit CEPA. Thanks to Raphael W. who permit to share this very rare photo.
