Here is a hole filler until something better comes along. This CD 104 is the base embossed Standard Glass Insulator Co. Boston. Mass. This poor devil has many, many cracks base to dome and back and every which way, but it is still all there. The photo is of the best displaying side. I`ll also post a photo of the base. There is a chip that removes most of the GLASS embossing. Being somewhat less than mint I`ll back off the regular three hundred dollars and ask but $40 and that includes shipping.
