This telephone dates from
the US entry into The Great War and looks surprisingly modern
compared with the British and German couterparts. Made by the
Kellogg Switchboard Supply Company of Chicago, Illinois probably
in 1916, it includes a morse key and a buzzer for sending and
receiving morse code. It is very heavy and has a substantial
magneto for generating ringing. The top lid is missing but as
this is a simple pressed steel affair it will be easy to make
The outer case appears to be
oak and is reinforced by heavy angle iron. The handset carbon
microphone is powered by a pair of 1.5volts cells. The original
types have been replaced by a pair of "D" cells. These
are leakproof types (see below) and look about 50 years old.
As it should look, with lid
These are the two U2 cells from
20 cents each
Assuming a dollar was five bob, 20 cents
was a shilling and for those who don't know, or have forgotten...
a shilling is 5p.
Any battery experts able to
date these U2 cells?
