Hmm, I can somehow see this as still a working prototype in 1934. Stable and marketable ones may appear as late as 1944, and some experimental military ones developed by then, but only used rarely/made it too late to turn the tide of war (kinda like the twin-jet Messerschmitt, maybe)… Still, it would be a somewhat better (though fuel-consumptive) analogy for a helicopter…
