Later developments From 1931 pneumatic tyres became standard, as by now improvements in technology made these more robust. Treadle operated "dustless shutters" were offered from 1927, hydraulic operation of the shutters was introduced in 1929. In the same year a fully enclosed cab with a compartment for loaders appeared. Mk II Freighter with Fore & Aft (F&A) body In 1949 S&D fitted a Fore & Aft tipper body to the Freighter. Based on the German Faun design the body could be regularly tipped forwards to compact the refuse. This basic design was to become a popular specification for SD vehicles for over a decade.
