Talkback indicator—commonly called a 'barber pole' due to its black-and-white stripes—for the Apollo Lunar Module, measuring 1.75˝ x 1˝ x .5˝, sealed in its Grumman packaging with "Read Before Opening" tags. An affixed Honeywell parts tag reads: "Flag Display Indicator, Mfr Part No. JG913A2, Series 5, Serial No. 238, Part No. LSC350-80404-09, Contract No. NAS 9-1100." 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.
