Translation of the above item:
LATHAM 49
The Latham 49 (if the designation is exact) was a mysterious machine, a flying boat with two tractive engines mounted between the two sesquiplane wings, the propellers being of the two-blade type. It was equipped with a nose turret and a rear one. The cockpit was not enclosed. It seems the aircraft did fly at Berre and Saint-Raphaël, but was never accepted by the Navy, despite its carrying their colors.
