Actually, my memory was flawed. The transcription disks were 16 2/3.

The Library of Congress has a large collection of 33 1/3 rpm large platters
that were made for the military for broadcast to the troops on Armed Forces
Radio. Pretty sure they were 33 1/3. Off to Wikipedia now...

Who remembers transcription disks? Radio shows were distributed to the
radio stations on large diameter 78 RPM records. That was the reason for
the "island" turntables in radio studios, to allow overhang of the large
disks. They eventually went to phone line networks. Early television
was
distributed over the phone line. The T1 line was designed to carry one
television signal.
I don't "remember" them - at least not as 78s - but I know what they were.
When I encountered them years later they had migrated to using standard
size 33-1/3 rpm LP records.
