Manfacturer: Gilmore
The lamp here is the Gilmore carbon filament light bulb, dating to around 1901-05. I call this the "doorknob" because of the odd squashed look. I believe this was used as a sign lamp at one time. Check out the photos here, and you can see that the bulb still works.
Lamp lit at reduced brightness on a socket equipped with a dimmer.
