U.S. Machine Cancel Finder -- Dashed/Dotted Horizontal Lines

Updated July 8, 2011

Your machine cancel was most likely made by a machine sold by the Doremus Company. There was a rare cancel machine that impressed dashed lines as a receiving mark. The much more common Doremus machine is designated as the type "C". This machine had a killer made up of dotted horizontal lines. Another machine type from this company impressed dashed horizontal lines.

There is a bit more information available about these machines on my Machine Web page (Doremus) and (Whitehead).
