Altimeter, Sensitive, Type C-14A, 35,000 ft, US Navy WWII 1537-2F-B
Here is a WWII-era Sensitive Altimeter, Type C-14 (also AN-5761-1), made by Bendix, part number 1537-2F-B as made for aircraft of the US Navy. The C-14 Altimeter was used across a wide number of aircraft of the US Navy and US Army Air Corps, including heavy bombers B-17 and B-24, medium bombers, B-25 and B-26, Fighters P-38, P-39, P-40, P-47, and P-51, and transports C-46 and C-47. BU AERO US NAVY is embossed on its face.
The C-14A Sensitive Altimeter displayed altitude using 3 pointers. The first and longest indicated 100's of feet, the second indicated 1000's of feet, and the third and smallest indicated 10,000's of feet. The photos shows the first two pointers, and the smallest pointer is hidden behind the 1000's pointer. The knob is used to adjust the altimeter to the barometric pressure as displayed in the small window at the 6 o'clock position. See spec sheet in the photo gallery.
It is clearly experienced but in reasonable condition given its age. The glass and case are intact, and the knob rotates, but only intermittently changes the barometric display, and the pointers. Measures 3.25 inches diameter and ~4 inches deep.
