The Richard Perkins warship identification albums form one of the most detailed studies ever undertaken of the changes to the appearance of Royal Navy ships. However, it is a unique hand-drawn manuscript artefact in the care of the National Maritime Museum, so despite its value it is rarely seen by anyone besides the museum's curators, for whom it is a precious resource, used on an almost daily basis.

In collaboration with the Museum, Seaforth is undertaking the first publication of this monumental work in a superbly produced multi-volume edition that captures all the qualities of the original. Every page is reproduced at full size, making the extensive hand-written annotation readable, while the fine-line drawings retain all the colours that Perkins used to denote appearance differences and alterations.

This final volume of the series reproduces all the remaining material from the Perkins albums, covering convoy and minesweeping sloops of the Great War era, interwar escorts, mine warfare vessels, and important naval auxiliaries, like survey ships, depot ships and Admiralty tugs. It even includes the sketches and unfinished material that form an appendix to this mammoth undertaking.

This is a publishing event of the utmost importance for every enthusiast and ship modeller, who for the first time will be able to own a copy of a unique and invaluable reference work.
