Comments	Thought to be a broken pin version of David Williams original pattern 2-5. Examination of these stamps reveals blind perforations where the 7,8 & 9 holes were supposed to be punched. Apparently this die was loose and sometimes the holes would be left blind and other times they would not show a punch at all. This appears to have started happening April 1910.
