These are not the pre-1929 music discs, but rather the later ones used in the Voicewriter office dictation equipment. The discs are 7" in diameter, made of thin red plastic. One side of each disc has the Edison signature trademark, the other is labeled "Diamond Disc". An interesting curiosity for the Edison collector and a great display item.

I am selling 2 discs for $3, or an original envelope of 10 discs for $10. Postage $3 in the USA, elsewhere at cost. Please PM or email to order or ask questions.

A couple of envelopes of 10 and a few singles left. If you want multiple envelopes of 10, I will sell them for $8 each.
