American Light Aircraft, From Little Known Designers

[hesham]

From Modern Mechanix 1934/12,

here is a pivotal wing monoplane concept,from Mr. Jacop P. Sellmer.

Hardly 'novel' when one considers that Frits Koolhoven employed the feature in his F.K.30 Toerist some seven years earlier.

If you absolutely wanted to create a topic for this particular aircraft (which to me is completely pointless), at least you could have made the title a little less lazy and generic... How about "Sellmer pivot-winged plane (1934)"?
Or maybe you wanted to start a topic about ALL little-known US pre-war aircraft builders? In that case the title should be "Little-known pre-war American homebuilds" or something similar (the term "designer" is deceiving, especially considering many of those pre-war guys worked in their barn following a trial-and-error method — most of them were no engineers!).
