Breguet military airplane, type 33 : a two-place long-distance sesquiplane for observation and bombing
This is a 1931 NACA aircraft circular, issued by the National Advisory Committee for Aeronautics, describing the Breguet Type 33 two-seat sesquiplane built for observation and bombing. Its photographs are plain black-and-white views of aircraft mountings, cockpit instruments, a gun mount and a fuselage tail, with clear numbered captions a designer could use for technical reference on aircraft interiors and machinery.
