I have a have and have seen several WWII Gem, Red Cross and other discs but
the original poster, on another list, states that they are definitely "45"
I have a 7" lacquer disc blank with the "45" center hole so they were
available. That may have been a likely format to use during the Korean war era,
since a "45" player would have been more universally available than reel
tape, or even a 78 turntable late in the decade.
Of course during the 50's and 60's, there were many more alternate means
available to "call home" than during WWII, but if one wanted to send a disc
recording, the "45" format could make sense then.

These records were very widespread all over the country and in some of
the major points of encampment around the world. But there is one thing
that is very important for Ms. Denman to know about them -- they are NOT
45s, they are 78s. There was no 45 speed until 1949.
