Thank you. You know, now that I give it a closer look, I see how it's different. I think I know what this balance is now, and it may be a custom order. Before I can confirm though, can I see a few pictures of the underside of a bottom shoe still installed in the balance? I want to see if there is a wheel in it. I would also like to see a closer picture of the metal tab at the end of the string. We can then work from there.
