Seversky Bombing Control for Aircraft Photographs
In the years following World War I, the US Army Air Service Engineering Division at McCook Field, Ohio worked to develop improved bombsights. One such project, undertaken with the Sperry Gyroscope Company and Alexander de Seversky (the designer), produced the Sperry Type C-1 bombsight, which used a gyroscopic stabilizer.
This collection consists of ten black and white photographs of bombing control instruments and equipment designed and manufactured by Alexander de Seversky and the Sperry Gyroscope Company, circa 1923. The mounted photographs, which measure 12 by 10 inches including the mount and are labeled, include views of the sight cradle, the gyroscopic stabilizer mechanism, the pilot director mechanism, automatic machinery for logarithmic spiral drums, and the installation of the complete Sperry Type C-1 bombsight in a Martin bomber.
Collection is in original order.
