About the Armstrong Siddeley 12 Plus/Fourteen
The 12+ was produced between 1936 and 1939, with a total production of 3,750 vehicles (which includes the 14).In 1935 the 12HP was complimented by a model with increased power, being known at first as the 12+ (Twelve Plus). A change was made to the pushrod overhead valves, now being slightly inclined and fed by a horizontal carburettor through an alloy manifold. The cylinder bore was now 61mm with the 95.2mm stroke still being retained from the 12 engine resulting in an engine capacity of 1666cc that provided 45bhp.
Wheelbase was lengthened to 9' 0" and the chassis was now a box section. The differential ratio was altered to 5.3 to 1 and larger tyres were fitted allowing easier running at touring speeds.
Both 4-light and 6-light saloons were produced
In 1936 a centrifugal clutch was fitted as a further refinement and the car then became known as the 14.
The magazine Practical Motorist of March 1937 said that it was “a very refined car, solidly built and with a certain air of dignity. The car is not one for the sporty boy but for the more sedate and those who take pride in ownership of good things. From every angle it has the appearance of quality, so the price of £320 is fully justified by the product.”
