Query: an excellent ship-by ship history of british WWI blimps

This book is an excellent technical history of WWI British airship design. You will find here the design, service history, and a photo of every British airship that entered naval service from pre-war beginnings to the end of military airship operations in the twenties. Included is a detailed map of all airship base locations, a description of mooring techniques before the mooring mast was invented, and a description of flight operations. It is not a campaign book, or a memoir book, but the wealth of technical information should satisfy most ardent blimp buffs.
