Awesome little plane I want the version with the pedestal mounted twin machine guns !The "Two Wings Mariner" ultralight flying boat that had been flown by Harvey Cleveland (several YouTube videos available) is the only small homebuilt along those lines that I'm aware of.
Monoplane, single-engine, 1.5 vertical tails, 37.5 foot wingspan, with inflatable floats?
Of all the quirkier WW2 airplanes, this has always been my favorite and I spent many hours doodling up something similar, which will never see the light of day. A long time ago I spent a few days volunteering at the RAF museum in Hendon, where I could drool over this to my heart's content. That and the Stranraer.
