Eight pages of illustrated explanatory and historical text (I think in translation) and constructional details are followed by 58 pages of very elegant detailed colour pictures of the boats and their deck equipment and its arrangement from several different angles, about 160 in all, covering a 1942 S38b armed with guns, torpedoes and depth charges, and an S100 from 1943 where the last were substituted by mines. The quality of artwork, apparently developed from a 3D computer model, and production is superb.
Included with the A4-size softback book is an A2 drawing showing port, starboard and overhead detail with the S38b one side and S100 on reverse. There are 55 other volumes advertised at the end, illustrating ships from battlecruisers to submarines from six different navies. Anything in this series would be a perfect gift for a model maker, so completely is the subject visually covered.
