WHO FIRST FITTED A CENTRIFUGAL OIL FILTER? Sir,

With regard to your note on the Simca woo, you refer to the centrifugal oil filter as being introduced by Fiat.

Apart from the type which has been made by Glacier for a number of years, I recall that a crankshaft-mounted centrifugal filter was fitted to the engine of a Russian car a considerable time before it was adopted by Fiat.
