Label inside the back door of two of
my Warren Auxiliary clocks that do not have the Telechron name on the dial. These labels are believed
to have been printed in 1918, before the synchronous motor patents were
granted. The labels do not have the "Telechron" trademark, which was first used in 1919.
Label on the bottom of a 3 inch dial tambour cased Telechron clock made about 1925.
