I found this old x-ray tube in the trash on the side of the road. It is in a very unique shipping crate. I have researched it and I belive it to be a early version of the "coolidge tube". If I collected bulbs or tubes I would want this one. I would be gratefull for any advice/help.It may or may not be for sale. If I knew how to download pictures here I would. I can e-mail them to anyone who might want to get a look at it.
