A suggestion, most modern turntables are not flat enough for these
discs, place a piece of board or cardboard similar in size and shape of
the disc with a hole in it to create a flat surface. You might need a
small piece of tape on the back (if one sided) or near the edge if
cardboard surface is too slippery.

Dear Barbara Need,
If the disc is translucent green vinyl, it may be a Soundscriber
disc. These were 33.3 rpm microgroove, so you should try to play it
as if it were an LP. Pray that it hasn't warped; if it has, you may
need to send it to someone with excellent equipment and much experience.
