U.S. Machine Cancel Identifier – Columbia with Wavy Line Killer

Your machine cancel was made by a machine sold by the Columbia Postal Supply Company of Silver Creek, New York. The machines made by this company generate a wide variety of markings. This later marking can be confused with those made by other manufacturers: just one of the reasons why this ‘machine finder’ system was devised. The year date can be seen to occupy one line near the bottom, but there are other styles where the entire date is on one line with the year as only two digits.
