Subject: Parabolic Reflectors in Early Signal Lantern Research
Here's an image of a parabolic reflector. There were many different syles but the one common thread seems to be the inset mirrors at angles. Some are of the simple sunburst variety.
Should you find out anything more on the description of the lamp in your parent message, we'd all be interested in seeing it.
