engineers-- I need advice!!!

Amidst all the wonderful stuff I got from Eunice Randall's home was
something I had never seen before.  It looks like a record (a BIG record,
like the old 78s only larger, like an lp from the 1970s) except it is made
of... steel, or perhaps aluminum.  It says on it "do not use steel needles;
use only fibre or bamboo needles".  I know we have some collectors on this
list-- what do I have, and what do I play it on?  I'm assuming it is some
kind of transcription, but again, I never saw one that is so obviously NOT
vinyl or wax..
