deep wading kits
Guys, here's what I can tell about deep wading kits without having my references at hand.
The British deep wading trunks differed from the US-built ones. These had the scoops on top, whereas the British ones were just plain rectangular open ended ducts. Also, as the different types of Shermans had different engine cooling arrangements, the deep wading kits varied from type to type.
Mark's picture 1 and 2 show the British kit for an M4A4 (Sherman V) with multibank engine. The M4A4 has a liquid-cooled engine which draws in cooling air in through the turret hatch, so only one duct is needed at the rear for the expelled cooling air and exhaust gasses.
Picture 3 shows the US kit for a radial-engined Stuart (M3A1?), whereas picture 4 shows the setup for a radial-engined Sherman (M4 or M4A1). Radial-engined tanks had a separate air intake on the rear hull deck to allow large quantities of air to be drawn into the engine compartment. Like Mark pointed out, the front duct is fitted over this air intake.
All for now,
regards,
Hanno
