Looking for a Music Volute!

[cwalton]

Hi!
I am looking for a Voluta musica in good condition with very clear "notes" and markings, as I would like to try to write a song from them.  Information on the shell would be nice but is not necessary.  It's for a school project so a price on the lower side would be helpful. I'm probably going to end up buying a few of them, but haven't seen anything online that I can work from.
Thanks!
