"Lambert was a drafter of no mean skill ... his drawings are concise, clear, and invaluable to scratchbuilders and super-detailers. Very highly recommended!" -Nautical Research Journal John Lambert was a renowned naval draftsman whose plans were highly valued for their accuracy and detail by modelmakers and enthusiasts. By the time of his death in 2016 he had produced over 850 sheets of drawings, many of which had never been published. Now they have become available in these remarkable collections, with expert commentary and captioning included. The initial volumes concentrate on British naval weaponry used in the Second World War, thus completing the project Lambert was working on when he died. His interest was always focused on smaller warships and his weapons drawings tend to be of open mountings-the kind that present a real challenge to modelmakers-rather than enclosed turret guns, but he also produced drawings of torpedo tubes, underwater weapons, fire-control directors, and even some specific armament-related deck fittings. Following the earlier volumes on destroyer and escort armament, this one covers the multitude of weapons carried by Coastal Forces, many of which were improvised, ad hoc, or obsolescent, but eventually led to powerful purpose-designed weaponry. An appendix covering the main deck guns carried by British submarines of this era is included, along with an introductory essay by naval ordnance authority Norman Friedman and a selection of photos.
