1902 4c brown, imperforate, Schermack type III, wavy line machine cancel, design fully clear of the margins on all sides with Schermack perforation at right, trivial toned spot not mentioned on accompanying certificate, only 40 examples recorded, with 1972 PFC. (With the rising popularity of vending and affixing machines, the Bureau of Engraving and Printing received numerous requests from manufacturers for supplies of imperforate stamps, which could then be privately perforated to conform to each firm's machine. In May 1908, a supply of 25 sheets (400 stamps per sheet) of the 4c 1902 Issue, without perforations, was delivered to the Schermack Mailing Machine Co. in Detroit. The entire supply was cut into coils with Schermack Type III perforations, designed for the firm's patented affixing machine and delivered to the Winfield Printing Co. for use on mass mailings of advertising material. Approximately 6,000 were used on a mailing for Hamilton Carhartt Manufacturer, and almost all of the 4,000 balance were used on a mailing for Burroughs Adding Machine Co.) (Cat No. 314A) (Image)
