I looked at the bulbs in a clockwork-averaging sextant I have here. They are fairly small, but have bases with room for an led to be
soldered on if one broke the bulb first to get at the wires.

This sextant is labeled

Sextant, Aircraft, Periscopic

MS28011-6

28 volts A-C or D-C

Specification MIL-S-5807C

.....Etc etc etc....

The maker is Kollsman Instrument Corporation
