Old technology, been around since WWII, after No, they are much larger than that. The base is about 4 mm diameter (eyeball, I didn't caliper). The bulbs I knew as "grain of wheat" didn't even have bases, just a pair of fine wires fused into the glass. That is why I identified the particular sextant. It may be that the original message was about one that did use 'gow' bulbs. It would not be at all difficult to mount LEDs in the bulb bases in my sextant.
