I'm with Bo.....I doubt it was ever built, even as a single prototype. I am sure we'd have heard of it. And, as they are American plans, I doubt they'd have any relation to the Felixstowe. Granted, F'stowes were used by the Americans and some Curtis planes were used by the British, but this just never seems to have gotten off the drawing board...literally.
I will send these to a couple of my dad's colleagues who are still living....maybe someone will have some ideas.
Yes, Terri....it would make an amazing model! I have to say it occurs to me to just do the hull under construction as a diorama. It would be a lot like doing a plank-on-frame ship model. We just need to make the days 50 hours long, is all.
