The Laté 673 was a gem for Tophe ! A project for a single engined, twin-boom
floatplane fighter with a tractor prop and retractable floats. It was a pre-war project.
the Nord 1800 is mentioned in "Les Avions De Combat Francais", but without drawing, too,
and the SOCATA X-270 and a NC.1150 are unknown to me.
We need some kind of visualisation ....
