Apollo Lunar Module Group of (2) 'Barber Pole' Talkback

Group of two talkback indicators—commonly called 'barber poles' due to their diagonal black-and-white stripes—for the Apollo Lunar Module, each measuring 1.75" x 1" x .5", sealed in their Grumman packaging with "Read Before Opening" tags. Both bear Honeywell parts tags reading: "Flag Display Indicator, Mfr Part No. JG913A2, Series 5…Part No. LSC350-80404-09, Contract No. NAS 9-1100." They are marked as serial no. "242" and "243." Mounted on the instrument panels, 'barber pole' indicators were used to denote the status of various systems: when covered by a gray flag, the system was operating as normal; in the case of an abnormal or in-progress status, the flag would be actuated to reveal the 'barber pole' as a visual indicator. In overall fine condition.
