TED - Two frequent posters here have published several books explaining the origin of these little tractors. There's a pretty little blue square above this form with a real nicely restored 122 on it.... Click on the square and get your credit card out.... and enjoy the reading. Hank actually did a REAL fine job on this book.... and Apostle Ken Updike has two books out on the FARMALL CUB and CUB Cadet tractors. As Hank & Ken kidded a couple weeks ago there are RED BOOKS, BLUE BOOKS, and Yellow Books.
