In England all "B" engines were serialled on the block pad . The law required that the engine itself must be serialled . AA trucks in England were built into 1936 . I had a 1935 AA with AA 4981139 stamped on the block . These engines had a "B" oil pan with no shroud attached . This is just to clarify if someone has a "B" engine which has a serial on the block ,they are a more robust engine than the Detroit engine with a thicker top deck and are not prone to cracks anymore than a "A" engine .In WW2 they were used in welders ,generators etc etc and some ran on kerosine with cast iron pistons and special exhaust heated inlet manifold . More astounding useless information !!!

John in same place same weather .
