DeBence Museum has a Symphonion 30A disc music box, and we have some
13-5/8 discs which are the correct diameter but they do not play
properly.  This box uses style 30 discs.  What do they look like?
Specifically, do they have holes around the outer edge?

If the answer is no, then that is why our discs do not play properly.
If the answer was no, then where can I find some proper discs?
