The head and tail of the spine strip is damaged with loss to the tail; also along 4cm of the tail the hinge is split,causing the front cover and front end paper to be partially detached. It's not a pretty copy, but the binding is good and the pages clean, apart from annotations and diagrams on the back end paper and a neat ownership signature. 90 pages. The book's subtitle is: 'a concise and reliable guide for the wireless amateur in the construction of his apparatus and to the better understanding of his hobby.'
