U.S. Machine Cancel Identifier – American Straight-Line

Your machine cancel was made by a machine sold by the American Postal Machine Company. The most common, and most popular collected machine is the American ‘flag’ cancellation. This type, however, with a 6-bar straight-line killer, is far less common. Note: the American company made machines that impressed various types of straight-line cancels in the late 1800’s. These are not normally included in my ‘finder’, since they fall before the Postcard Era. These later straight-line cancellations appear from about 1909 to around 1920.
