First Steps in Navigation by the Stars
By Frank Debenham OBE, MA.
Second Edition. June 1942

Interesting book for your navigator's case.
Hard back with dust jacket. The book had been flattened when open, presumably to make reading easier. The cover is a little faded and has wear to the edges and tears.
