Ron, I don't remember where I found it. It's a small paperback, 4" x 6 3/4", red cover, with a picture of a guy tuning in a factory, looks like, on the front. It's one of a series of books called The "Amateur Mechanic and Work" Handbooks by Cassell's Publishers, London. Check Alibris Books or ABS Books on the Web, and maybe a used copy will come up somewhere. --David Nereson
