Vintage Benjamin Enamel Green Gas Service Station Light industrial steampunk. There are some holes in it and the inside was apparently painted. I have not tested it. It appears to be a large base socket. Enamel is missing from it. There is rust on it and it appears that the fitter on top is bent and that may be seen in the pictures. Please use the pictures to help determine the condition of this item. I am selling this item as is.
