This indicator has a service label from the NARF (Naval Aircraft Rework Facility) Alameda CA, stamped Jan 1970. The floating ball indicator no longer contains damping fluid, so the ball glides but not in fluid. The dial markings are clear and the glass and case are intact. See photos. Measures 3. 25
