Here is a WWII-era Sensitive Altimeter for Parts or Repair, Type C-14 (also AN-5761-1), made by Bendix, part number 1556-2K-A 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 show 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.

The knob rotates but does not turn the barometric reading. The glass and case are intact.  Measures 3.25 inches diameter and ~4 inches deep.
