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 (when attached) 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 has broken at its stem but is included. The glass and case are intact. Measures 3.25 inches diameter and ~4 inches deep.
