Commercial Electrical Supply Company straight shaft desk set

At a glance this looks like several other common candlestick designs from the early 1900s but once you see the ad and look closely, it is a very rare candlestick from the Commercial Electrical Supply Company in St. Louis. It is a common battery, No. 52 desk phone. The ridge in the base makes it different than other more common telephones. This particular candlestick has a Vought-Berger marked transmitter, and an older Vote-Berger marked receiver. Great candlestick.
