3,000 Mk IIs had a "beetle back" body. This had two doors, only two small windows on the right side and one on the left side, and an all-metal roof with two revolving vents. The later Mk IIs and approximately the first 4,000 Mk IIIs had a later type of "beetle back" with an additional small window on the left front side and windows in both doors. A canvas roof was mounted on a cruciform steel frame over the crew compartment, and there were two square vents in the roof behind the canvas section. The vehicle also had larger fuel tanks and filler cap surrounds. The last 2000 Mk IIIs had a "Number 5 body", which was a new design with a square shape and a complete canvas top with two circular hatches, and four doors with windows. Once the 18-pounder and 18/25-pounder had left service there was no requirement to carry the gun's traversing platform on the roof. The brackets for this were duly removed, and usually substituted by a framework to provide an additional area for the storage of kit. See also CMP FAT, a similar vehicle by Chevrolet. Early models had very similar bodywork, but can be identified by a four-sided windscreen glass, compared to the five-sided Morris Quad screen, with the upper corner cut away.
