Thanks to all for the amusing and helpful responses to my question about our light bulb! Thanks also for the reference to the light bulb museum below. I found it as the Mount Vernon Museum of Incandescent Lighting (if anybody else needs ot know). I'll contact them. Thanks everybody and happy light bulb changing!

I contacted the owner a few years ago, when I was looking for a selection of historic light bulbs to use in an exhibit. I do not remember his name, but he was very knowledgable and helpful. Good luck. Ceres Bainbridge
