What is your favorite recommended Oliver book for my 85 year old fathers birthday gift? He started farming with a little 60, later a super 88 which has become a parade tractor, 1755 which we outfitted with a 5.9 cummins and repainted this winter, a 2255 which we unfortunately sold 10 years ago, and then a 2-105. Thought a good read and pics would entertain someone who spends a lot of time indoors. Thanks, Dennis
