Thanks for posting! I am confident we can provide you with the replacement balances you need for your repairs. Although, I will need to see the top attachment from the balance to identify the right series. I'll also need to see the bracket connecting the spring and the string in the middle of the balance.

Please don't hesitate to reach out with any other questions in the meantime.
