OT,but yes there are acetate/lacquers with 45 size holes.I have a couple of pretty much unknown soul and country artists from the 60s and 70s,and yes these were produced by professional studios.They are rare,but they do turn up.

During WW II??????????? Besides, of the tens of thousands of lacquer
discs I have seen over the years I have come across exactly ONE 7-inch
lacquer with a 45 hole, and it was a professional grade heavy-weight
Reeves-Soundcraft from 1959. I have looked thru the catalogs of disc
blanks and found very, very few listings of large hole 7-inch discs.
Non before the mid to late 50s, and none at less than thick, heavy
professional grade. Of course the blanks used were custom made, but if
they had a large hole the recording machine MUST have a spindle adapter.
And if they recorded at 45 they would have to have been adapted to that
speed. And cutting microgroove also required modifying the feed-screw
and using more fragile microgroove cutting needles. If they indeed
continued to record these discs during Korea they would have done them
at 78. They used cheap thin home-grade discs, and a large hole would
weaken the disc, and microgroove is difficult to do well on cheap, thin,

The Korean War was over in 1953, which is EARLY in the decade, at which
time the 45 was NOT more universally available than a 78 turntable.
Besides, we and the poster are not discussing the Korean War, ONLY WW
II. Her organization is the "Institute on World War II & the Human

But we were not discussing anything but WW II. By the late 60s they
would be using cassettes, and many of the soldiers would have or have
access to personal cassette machines.
FYI, the photo she sent me shows a Gem Blades, a Wilcox-Gay Recordio
with what seems to be a fibre core a nd a yellowed clear lacquer
coating, and two special labeled discs with black lacquer. All
obviously 1940s vintage, pre-45 speed.
