We all may be right:

--A large cluster of high grade cards many hand cut found in England probably never did see the inside of a pack;
--The fact that the set had an ACC number means it is known from back in the day so likely not only a non-issued cluster of cards.
--I am certain that there are some other cards in the hands of collectors who do not share their holdings publicly and who do not slab their cards.
--Odds are that the issued Pirate cards were only a tiny part baseball, Judging from the variety of NS cards. None are easy to get.
--I have been chasing UK issued foreign export boxing cards for years. They show up both from the UK and Asian sellers from nations that are fully integrated into e-commerce in the collectibles field. China is not one of them. Cards I have seen from Asian countries that were war torn in WW2 are very scarce. I don't think much that was there survived the Japanese war machine. Thus far I have only gotten one prewar UK export card directly from an Asian seller and I have been carefully trolling Asian selling sites for years.
