S.H. Couch Telephone Co. 30 station Autophone desk set

Rare, S.H. Couch 30 station Autophone intercom. This one is very dirty, but you can see the dial clearly. Marked with tag on the base.  These were used in the pre-dial era (Western Electric Bell phones did not introduce a dial until 1919). The Autophone could be used in a small business where everyone would have a unique extension and could buz each other directly without the need of a switch board operator.
