Whitebox 1/43 Bentley 3 Litre 1924 (green) WHI171

The 3.0 L straight-4 engine was designed by ex-Royal Flying Corps engineer Clive Gallop and was very advanced for its time. It was one of the first production car engines with 4 valves per cylinder, dry-sump lubrication and an overhead camshaft. The four valve SOHC Hemi design, with a bevel-geared shaft drive for the camshaft, was based on the pre-war 1914 Mercedes Daimler M93654 racing engine.
