We have been trying to help a lady identify the tunes on her
3-bell cylinder music box.  Only one is identified so far,
courtesy of Jochen Kopf; it's felt the tunes may be hymns.

I'm sure the owner would be grateful for any assistance.
If you know any of the tunes, please answer on the YouTube clip.

Thanks in advance,
Mark Singleton
