I've wondered if the wierd looking G you see on almost all variations of B.G.M. CO. insulators was part of their trademark. Interestingly, the piece with the milky olive swirls on the right is the first I have ever seen embossed which does not have that characteristic looking G embossing. Its sort of the Marilyn of the Munsters as far as B.G.M. CO. embossings go.

I would be interested in hearing from others who share an interest in Baltimore Glass Manufacturing Company - B.G.M. CO. insulators. I am always looking for variations I don't have and those with milky or olive swirls to add to my collection.
