Glen VAnother Oops. There is a letter for coffee. Forgot about the Arbuckle trade card, which is a K-7 or K-9 (arf, arf). Anyways, that would make the Voskamps a K-Unc.
OBC has a great web-page for type collectors: http://www.oldbaseball.com/refs/typecards.html
It lists all the ACC catagories. Also, it has a spreadsheet of card issues that can be downloaded. In excel, it's easy to sort on different columns and set it up by year, ACC type, set name, whatever.
