Hi my mother has a one filament (looped to look like two filament)light bulb medium base with the words WABASH RY. etched on the glass by the base of the bulb. Also there is an oval sticker with the words Westinghouse on top of oval and Carson at the bottom. It says it is a 50watt bulb. There are three numbers on it as well 115,118,and 111. There is a picture of a nail spike under the Westinghouse words. Also there is a tip on the non base end of the bulb. It looks like the Westinghouse metalized but has the word Carson instead of "metalized". I would post a pic but don't know how. Any info you could give would really be appreciated. She got it from her grandfather who worked on the railroad in early 1900s.
Thanks
Tori
