Incredibly detailed, authentic World War I original gelatin silver photograph capturing the interior cockpit instrument panel of a military aircraft. The reverse side features the original purple ink stamp from the historic "Wilbur Wright Aviation Field" in Fairfield, Ohio, attributing the work to Assistant Post Photographer Pvt. J. L. Kreis. Based on official archives from this specific photographer at the base, this photo captures the instrument configuration of an early American Army fighter/advanced trainer, specifically matching technical assessments conducted around late 1918 (such as the Standard E-1 / M-Defense Scout program). Technical Details Visible in the Cockpit: Central Tachometer: Marked "R.P.M. HUNDREDS" and designated as a U.S. Army Air Service Type C centrifugal tachometer. Airspeed Indicator: Located at the top left, calibrated up to 130 M.P.H. and stamped with "U.S.A.S." (United States Army Air Service). Clear view of the wooden internal framing, cockpit controls, safety-wired components, and rigid turnbuckle bracing characteristic of Great War aviation design. Location taken: Wilbur Wright Aviation Field (Fairfield, Ohio) . Photographer: Pvt. J. L. Kreis (Assistant Post Photographer) . Date World War I (Circa 1918) . Photo Size: Approx. 6.75" x 4.75".. Excellent vintage condition. The gloss remains bold with high contrast and sharp focus. Minor surface age wear as pictured. Please review the high-resolution listing photos carefully to verify condition. A phenomenal addition for collectors specializing in early aviation tech, WWI military history, or specialized USAS airfield photography ephemera.
