Keystone Telephone Co. dial desk set

Fantastic Keystone of Philadelphia dial desk set. American Electric was the sole manufacturer of Keystone, Philadelphia and was considered a very strong competitor to the Western Electric Bell telephones, expecially their dial telephones, because Bell did not acquire Automatic Electric Company until 1916 and did not introduce a dial candlestick until 1919. This is a very rare telephone. Also has a marked, Keystone receiver.
