The 5960 (also TD-1 and S340) is a cold cathode gas trigger tube originally made by Bendix. This glass example was made by Sylvania (5960/S340) and has different dimensions than the original tubes. This tube was designed for high shock and vibration at extremes of temperature and pressure. They were used in ignition systems for jet engines.
