Keystone Subscriber Set

c. 1930's - Manufactured by Automatic Electric for Keystone. The exterior wood painted black seems to be a Keystone trademark.

Keystone Telephone Company #1 Monophone

c. 1925 - This model is known as the Automatic Electric #1 Monophone identified by its bakelite base, long cradle neck and surface-mounted dial. (Compare to the Western Electric AA1). This phone and subscriber set are displayed in the same condition as when removed from service. The telephone/subset were manufactured by Automatic Electric Co. who produced Keystone of Philadelphia equipment subsequent to American Electric Tele. Co. until Keystone was acquired by Bell in 1945-46.

On the cradle is a partially torn gold sticker with "EXECUTIVE TELEPHONE PROPERTY OF KEYSTONE TELEPHONE CO. OF PHILADELPHIA".

Has rare original Keystone card dial center with integrated number card under celluloid.

The Subscriber Set has the Keystone logo on front.

Keystone Transmitter Arm

Here is a beautifully refinished Transmitter arm with Keystone shaped base. The transmitter cup is marked Keystone Telephone Co. Philadelphia.

Examples of Keystone Wood Wall Phones

Most all phones and phone parts used by Keystone were produced by the American Electric Telephone Company.

I am looking for an American Electric Tele Co. fiddleback wooden wall phone (as shown) to attach the above transmitter arm. Also looking for nickel switchhooks with the Keystone shaped cutout for both the earlier manual candlestick and wood wall phone.
