Cambridge MD: Cornell Maritime Press, 1975. 44pp, 10 illustrations. Topics include scope power, mirrors, shade glasses, theoretical brightness, accuracy, workmanship, accuracy, comparison of specifications. It is available at the University Library, all locations, of The California State University for free.
