I personally acquired these from Carter about 1975. These are original prints 17 inches by 22 inches. They show ALL part numbers, machining specifications, and a history of parts being superseded. Prints were mailed to me folded, and I will mail them the same way. Prints are $75. each except the 3636s which is $100. to include mailing costs within the USA. MasterCard, VISA, or Paypal accepted. Still digging, may uncover more. Orders by telephone ONLY. I only have one of each, and I DON'T want two or more folks thinking they bought one. 573-392-7378 (9-12, 1-4 Mon-Tues central time).
