Crates containing Bedford engines for Churchill tanks. The Bedford Vehicles engine was effectively two engines in horizontally opposed configuration ("flat twelve") on a common crankshaft. There were four Solex carburettors each on a separate manifold that fed three cylinders formed as a single cylinder head. The elements of the engine and ancillary components were laid out so they could be reached for maintenance through the engine deck covers. Air for the engine was drawn from the fighting compartment through air cleaners. Cooling air was drawn into the engine compartment through louvres on the sides, across the radiators and through the engine compartment by a fan driven by the clutch. This fan blew the air over the gearbox and out the rear of the hull. By opening a flap between the fighting compartment and the engine compartment, this airflow could be used to remove fumes produced by firing the armament. The 1,296 cu in (21.238 L) capacity engine was rated at 350 bhp at 2,000 rpm, delivering 960 lb⋅ft (1,300 N⋅m) torque over an engine speed range from 800 to 1,600 rpm.

Allis-Chalmers HD-14 tractor by Richard Campbell The Allis-Chalmers HD-14 was introduced in 1939 and was broadly based on that company’s earlier and very successful Model L and LO gasoline powered crawlers. At the time of its introduction, the HD-14 was the largest track type tractor that Allis-Chalmers had manufactured and joined two other machines, the HD-7 and HD-10, which Allis-Chalmers had also released that same year. Over 6400 HD-14 and HD14Cs were manufactured between 1939 and 1947 when the type was discontinued.
