My 21 stud 1937 engine block has an oil hole from the timing gear area to each water pump and the water pump bushings are lubricated by the oil thrown off the timing gear. I believe the 1938-48 engines used the same method to lubricate the water pumps, per Joe Abbin's flathead book. So there would be an oil hole through the water pump gasket on the first and second generation engines.
