Telechron Motor Nameplates with Serial
Numbers
We present this data to help us organize
information about Warren Clock Co. and early Warren Telechron Co. clocks.
Early clocks have a serial number on the motor nameplate, and we guess
that the company stopped using serial numbers around 1930.

Above: Earliest Warren motor nameplate yet observed,
SN 2165.

|
Above: latest Warren Clock Co. nameplate, SN
56,967.
|
|
|
|
Above: earliest Warren Telechron Co. nameplate,
SN 59,430. The dial on this clock is labeled Warren Clock Co.,
so it is a transition piece dating to right around 1926.

Note: My files did not include a patent
from Oct. 3, 1923, a date used on nameplates in the early 1920s. I believe
this patent date was used in error, and the Oct. 3, 1922 date was the
correct date that should have been used.
