"Radio and Victrola shop"

Another treasure I found this past week. It's an electric sign measuring about 6ft in length. The letters seem to be made of half glass and half porcelain, and contain filaments. The letter is also anchored into a porcelain block which has two tracks for the wiring.

I don't know much about this sign regarding what type of electric sign is it and how old it is. The only manufacturing mark is "Chicago Miniature Lamp Works".
