Photographs of coastal gun training and documents relating to the donor's own training. The donor, John Crewdsen, came to Llandudno first as a trainee and later returned as a Gunnery Instructor. He has supplied the excellent information about the guns and processes for this catalogue and, on occasion, his own words have been used.
