Quite valuable anecdotal evidence .
Thanks for sharing this with us,David. I have long suspected this sort of clearance was necessary in these engines with iron barrels, but those who are supposed to know insist on using .003" and less . I have smeared two sets of pistons this way. I think we must remember that the old crankshafts that have not been cleaned out likely have constricted oil passages in them as sludge builds up over the years.
