If you don’t need a hard copy you can download a pdf of the Petzold (not: Petzgold) book here: http://www.flight-computer.de. And there is another new book on flight computers: Piel, Alexander, Dead Reckoning Computers for Air Navigation -History – design – inventors, Paperback A5; 338 pages; 157 Ill.., ISBN 9783753445748, Books on Demand; price: 25,99€ (I don’t know how much shipping would cost).
