15 MP Casey McGarr's 15 MP (SN 5491). “I believe it was built in 1964 but not sure. I bought it from Talley Printing in San Angelo, TX in 2002. The press was very clean and runs like a champ, I use my Vandercook #4 primarily but when I have a two color job I set up both presses.” The inking system is identical to the Vandercook SP15. Note also the angled cabinet.
