Kenneth, not sure if you mean the Lockheed jet seaplane fighter with hydro skis, or
the projects you mentioned in your quote "..late 670 to 673 projects.."
I've seen now, that there's a little typo, sorry.
It should be ".. the Laté 670 to 673 ..." for Latécoère. Those were single engined
floatplane fighter projects of the pre-war era. If you are interested , I'll post them in the
early projects section. About the Lockheed project, I think, there's hardly more, than was
already posted.
