WESCO Supply Co. desk set

Extremely rare 5 button WESCO Supply Co. desk set. WESCO got its name from acquiring the Western Electrical Supply Company in August of 1903.  WESCO manufactured telephones in St. Louis, Missouri. Great original telephone with metal tag on front of wooden base. "Solid" outside terminal receiver. I have seen a few WESCO wood wall phones but not another WESCO upright telephone.  Extremely rare.
