NOS unused Korry P/N 53-015681 or 53SB583 or 2026115540-001 radar threat indicator panel.  Not sure what aircraft these were intended for believe they might have come out of Hill Air Force base as early as 1971.  HAFB was depot for landing gear and the F-105 F-4 A-7 C-130 and various other aircraft.  The words on the indicator lights are in the third to last picture on the paper.  If you have any idea what these were meant to go in feel free to let me know!
