Check out this article reproducing a
Bell report on the XP-77 wooden lightweight fighter project and a proposed
successor at RetroMechanix.com:
The report provides an excellent history
of this unusual fighter prototype up to mid-1944, one of the best summaries
I've come across. The end of the document also features a proposal for an
improved all-metal version with a turbosupercharger and a bubble canopy, as
shown immediately above. The accompanying gallery features 37 images, including
several high resolution photos and drawings. It's great reference material for
modeling both the XP-77 and the improved version that never left the drawing
board!
