#2 - Western Electric CB wall phone

Unusual earpiece. You might be able to detect the "wave" in the shape where it meets the ear. This shape is to allow a "howler" sound to be heard by the subscriber if they have left the phone "off-hook" . The Howler was a high pitched tone that operators could connect to the line to alert subscriber s that their phone was off hook and therefore could not receive calls. The "wave" shape prevented the sound being completely closed off if the receiver was flat on the table top.

A rare addition to this Western Electric 312A telephone is what is often called the Phonopore Howler. I have a number of these with other Western Electric telephones in my collection and I have never bought one for less than $200. I have one available for $200 as an added feature for this rare telephone. The howler was typically wall mounted, directly above the 312A.
