Excellent challenge, evansb...
Except for the two engines...or, at least, two magneto switches... I'd wonder if this was the Bell XV-3 or the Transcendental Model 1-G, but I may be looking in the wrong category.
I understand this aircraft is not a helicopter, but was it an experiment in the VTOL/Tilt Wing field?
[Edited to remove erroneous "Model 200" reference and to add the Transcendental example]
