Columbia Machine Cancel

U.S. Machine Cancel Identifier -- Columbia

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 earlier marking can be confused with those made by other manufacturers: just one of the reasons why this 'machine finder' system was devised. Note that these 6-bar Columbia machine impressions are quite uncommon
