The Model 40 used steel tubing for the nose and curved wood-veneer laminate for the middle of the fuselage. The wings were wood and fabric. The plane was hampered by the antiquated water-cooled Liberty engine, required by the government in order to use up large stocks of surplus war equipment.BI231019 (hs3618)Maximum size:2402px × 1542px (~10 MB)8.0in × 5.1in (300dpi)License type:Rights ManagedKeywords:1920s-adults-biplanes-candids-day-dogs-exteriors-full body views-ground shots-historic production status-left rear views-left side views-mail planes-male-Model 40B-4-other livery-passengers and travelers-pet owners-pets-photos-posing-propeller planes-rain-sitting-stairs, lifts and ladders-standing-tarmac-text-three-quarter length views-two people-vintage / retro-wetRelated Photo/Videos:View All
