The actual machine for your cancel mostly depends on the date in the dial. In 1894, the American company made machines that impressed several wavy lines on the stamp (the so-called killer). Later, nearer to 1900, you will see this type of cancel made by an International machine. The wavy line killer for both brands of machine show 7 lines.
There is a bit more information available about these machines on my International Machine Web page, or on my American Machine Web page.
