Does anyone know what the phrase "C&DS means?" It is at the top of a
letter dated June 19, 1855 and reads: "C&DS - In matter of Perforating P.
O. Stamps". I have been trying to figure this out for several years, and
am hoping someone has seen this wording or similar phrasing in other
This letter was published in 1986 in The Chronicle in an article by Jerry
Wagshal dealing with what is called the "Chicago Perfs". These perfs
where actually a forerunner of official government perforations, and were
made on the first perforating machine made in the U.S. in the mid 1850's.
The letter was written by RK Swift, a banker living in Chicago, who acted
as a promoter of perforating machine on behalf of the inventor.
