Four Engine Tachometer Panel Segment OV-1 Horizontal SituationThis segment of a reproduction cockpit instrument panel contains two dual engine tachometers, both made by Kollsman (Type 740CK), a dual temperature gauge (AN5795T6A) made by Electric Autolite, and a red warning lamp. We have not identified what aircraft may have used the tachometer, but the dual temperature gauge was commonly used in aircraft of the US Army Air Force and US Navy. The tachometer pointers are labeled for Engines 1 & 2 and 3 & 4.
