Sorry for the delayed reply.
The two clues that you give are the time frame and the off-center hole.
Your disc is most likely 78RPM and was possibly made with one of the
commercial disc making booths available at Woolworth and many other
retailers of the time. It was popular during WWII for people to use
these booths to record voice messages to send to loved ones overseas. I
was told that Elvis Prestley actually used one of these booths in
Memphis to record a voice demo. Not sure about the Pepsi logo but if
it's a commercially made recording you will be much better off.
Anyway, these discs are VERY FRAGILE, most likely have a cardboard
center. Very few have survived the raviges of time and many of those
that have, are marginally playable due to surface cracks (crazing) ans such.
Start by playing your disc at 78RPM using an appropriate styli with
minimal tracking force and see what you get. Record everything you do!
You may only have one chance at playback and if it's off-speed, it can
be corrected. Use standard RCA Victor 78RPM EQ to start with. If it's a
little off, it can be corrected in the digital domain as well. I don't
intend to sound flip here but you probably have a voice recording and,
as such, have lot's of lattitude with regards to pitch and EQ settings.
