Схемка, я так понимаю, из Оспрея, посвященного Крусейдерам.
Английский текст оттуда (извиняюсь за ошибки распознования текста из картинки):
Known as the Mediuni Tank A/T 1, it consisted of a Covenantcr turret superimposcd upon a hull of enormous depth with the Meadows flat 12 engine situated deep within its bowels. Some 24t. tong, l3ft. wide and a massive 11 feet tall it looked unwieldy on dry land but seems to have performed well enough in the water. Built by Braithwaites of Newport in South Wales it was of rivetted Construction with all joints caulked to make them waterproof’ and a maximum armour thickness of 40mm. Weight was around 31 tons. The original model, whuich had no suspension at all, was replaced by A/T 1’, probably a. rebuild, which featured a sprung jockey roller at the front. This was followed by A/T l which had Churchill type coil spring suspension on all but the first and last two rollers, it was apparently rebuilt as A/T 1 about which little is known. Of the former two the folkning details are recorded. A/T1 employed the standard gearbox and Wilson steering system of Covenantcr while A/T1 was iittcd with the Sinclair Svnchro-Self-Shifting (SSS) system which was designed to give a much smoother changing sequence. Whichcver gearbox was used it was provided with an auxiliary box giving high and low ratio. The former, which gave a theoretical land spced of 21) mph, was only intended for ue afloat, when the tank would make about 5 mph. On land, especially across country, only the lower range was used to avoid damage, and that gave it a top speed of about 1(3 mph. A fluid coupling was also built into the transmission of both tanks to avoid any serious shock to the drive train when a tank first touched down during a swim ashorc. At sea the tanks had a considerable draught of 511. 6in. but a modest freeboard, to deck level, 01 titteen inches. The. crew numbered five; driver, three-man turret crew and what was described, in true nautical parlance, as an extra hand who shared the front compartment. It was his duty, no doubt, to operate the sea cocks on the ballast rank. This was located low down in the bow and its purpose was to aid traction on landing. As the amphibious tank neared the beach, water was admitted to the ballast tank so that the nose of the machine descended and helped to press the tracks down once they bit into the sand. Cross country trials were conducted at Qobham in Surrey with sea trials takii place off Barry Island in South Va1es, The testing authorities wcrc critical of the engine location, reporting that it was very difficult to work on, This is hardly surprising. In addition to being low down at the stern of the tank it was enclosed within an engine room, closed off by a pair of seel doors in a bulkhead. Crusaders were also fitted with deep wading gear for ship to shore landings over open beaches, although none ever took part in such landings apart from some special models such as anti-aircraft tanks and gun tractors.
