Amongst the Tildesley archives are some photos of this unusual Fordson. Ford discontinued building the Model F in America and established a new factory in Cork Ireland to build the improved Model N in 1932. These were the dark blue coloured ones with shorter "normal" wide fenders and the water-washer air cleaner with the inlet on the long steering column.
This tractor appears to be on trial somewhere in England, the rear end and fenders are Model F with the high forward seating position. But the engine has the water-washer air cleaner body which was introduced in the Model N in 1932. Note the rear wheel extensions.
There are no Fordson names cast onto the radiator sides nor on the header tank. The driver is wearing a clean white cover-all coat - is he a Ford employee? When I showed these photos back in 1984 when the book was published, none of the British Fordson historians could explain exactly what it is.
