The AF 3" bore engine block was cast at Fords Cork Ireland tractor plant where they had a foundry which Manchester did not . Final machining and assembly was done at the Manchester plant . The small bore engine was available in France and Japan and most likely in other countries who had a "horsepower tax" Vehicles fitted with the AF engine had a chassis number starting AF same as an A would with the engine number . The "F" indicates "Foreign" and RHD parts also carry an "AF" prefix . Late English built AA trucks have some parts that were only fitted in England and nowhere else these have AAE prefixes indicating England . Confusion has arisen as some English built AA trucks are described in period Ford adverts etc etc as AAF this did not mean they were fitted with the small bore engine it just meant they were not identical to a USA built AA truck as they were RHD . The small bore engine produced 28 BHP @ 2600 RPM . They were hard pressed to pull a Briggs Fordor with 5 passengers let alone pull an AA truck .

PS my 28 phaeton has the AF engine wich is way smoother than the A engine . It is fine in flat country but you can sure tell the difference on hills . Gas mileage is just the same .
