P.Bowers - Boeing Aircraft since 1916 /Putnam/

The first De Havilland 4M-1, a rebuilt wartime DH-4B using the Boeing-developed arc welding process for an entirely new steel tube fuselage.
A Boeing-built DH-4M-1T dual control trainer in service at Brooks Field, Texas, in July 1929. Note Boeing-designed US Army rudder stripes adopted in 1926 and Boeing designation on fuselage.
Boeing-built DH-4M-1s delivered to US Marines were given naval designation of O2B-1. Navy colouring after 1920 was all silver with yellow top to upper wing and tail.
Marine Corps O2B-2 with the rounded turtledeck that identified the -2 variant. The Loening COA-1 wings shown were fitted to a number of DH-4s and O2Bs without affecting their designations.
Boeing Model 16 (DH-4M-1)
Boeing Model 2, the C-4 seaplane, with small vertical radiators and parallel centre section structs. The apparent dark colouring is varnish applied over clear-doped fabric.
One of the three Model 3 seaplanes fully assembled inside the original factory building, which also functioned as a hangar. In the background is Mr Boeing's original Martin seaplane in the process of coversion to a landplane.
The C-1F seaplane, a single-float version of the standard C-650-699 (Model 5) with Curtiss OXX-6 engine. Standard Navy colouring in 1918 was over-all stone grey.
The C-700, a private machine built for William Boeing's use at the end of Navy C-650-699 production and duplicating the Navy trainers even to the use of military markings. Note reversed order of rudder stripes from 1917.
The C-700 modified to CL-4S by installation of improved Hall-Scott L-4 engine and reduction of aileron size to straighten trailing edge of wing.
Assembly line of Model C fuselages. The cylindrical tanks in the rear held compressed air for the engine self-starters.
A war-surplus Boeing C converted to a landplane by a private owner. The unreliable 100 hp Hall-Scott A-7A engine was replaced by a dependable 150 hp Wright-Hispano. Note the two-seat front cockpit.

BOEING MODEL 5 (C-700)
The first MB-3A, built after Boeing won industry-wide bidding for manufacture of 200 improved versions of WW-I Thomas-Morse pursuit design.
MB-3A with new redesigned tail surfaces as installed on the last 50 machines. Colouring of Army combat aircraft from 1918 to 1927 was khaki-brown (olive drab) all over.
Condemned Army MB-3A made available to the producers of the 1927 cinema epic 'Wings', who used it to portray a fallen German Albatros D-III pursuit of WW-I
Boeing designed and built its own propellers in the early 1920s. These four-bladers are for the MB-3A pursuit aircraft.
Women employees stitching the upper wing fabric of an MB-3A, circa 1922.
The MB-3A did not have a conventional instrument panel. Instead, the standard instruments were installed on the sides of the cockpit.
The first Boeing-designed aeroplane, the B & W of 1916, floating by the broad sloping ramp of the original factory-hangar.
The B & W being brought ashore.
The replica B & W taking off from Lake Washington.
The replica B & W made its first flight on May 25, 1966.
For demonstrations in Wichita, Kansas, and at air shows away from Seattle, the B & W 1A replica was fitted with wheels and brakes under the pontoons. These did not make the replica amphibious.
The front and rear cockpits of the first B & W. Note sparse instrumentation.
BOEING MODEL 1 (B & W)
Curtiss HS-2L flying-boat, the first of several non-Boeing designs that the company was to build between 1918 and 1927.
Model 4, the EA landplane. The undercarriage was not a true tricycle; the extra wheel was to prevent nose-overs by student pilots.
