Cosmopolitan Co. was a publisher and their control perfins are known on several of their publications. They began using control pattern 236 from 12/9/1909 until 2/9/1910. By 2/25/1910 they are known using control pattern 13. No idea why the switch, unless the first machine was a demo/loaner. The last known 13 cover is dated 5/2/1910. On 5/4/1910 a Cosmo cover shows pattern 137 indicating the 7 pin broke sometime between those dates. |
