Hi sorry I am glad to see a reply x) I know steemit doesn't give alerts, but are you referring to this video?

I may also have talked about it on another vid, I cant find it. I had one person attempt to make one for me with metal and it didn't sound too good :/ I think there's lead in the real combs that is required for a real monophonic tone, otherwise they sound like springs, hard to describe, it's just a no-go... maybe needs more experimentation.

I also replied on this video too:

The company I went with no longer produces them, but there was one that did digital recordings for snow globes (not the beeping kind, but they use real wav file recoridngs). For now, I have no one to make any metal printed ones for me.
