Wow!

The engine may be 2 turbocharged Wright R-2160 42 cylinders (7 Banks, 6 Rows) radial liquid cooling engine.

Great!


A while back, when I saw a rather worse copy of this drawing, I dropped it on an XP-58 plan. If you assume the propeller thrust lines coincide, you get a pretty close fit for the inner wing panels and fuselage width, and a span for our mystery plane of 67 ft.

Cool!
You solved the mytery of this fascinating connie like plane size.
R-2160 was very small compared with V-3420.
L-134-3's strong turret is very interesting. Also L-134-3 had contra rotating prop to keep ground clearance when take off and landing.
