channel balance
Thanks for reaching out to us! The shoe on the bottom of your balance appears to be completely damaged. This is an important factor in determining the replacement balances needed for your repairs. Would you be able to provide a photo of an undamaged balance shoe?
Please don't hesitate to reach out with any questions you might have.
Thanks for the photos. Its a bit difficult to tell from your original photos but I believe you may have a wingless top guide installed to the balance. If so, you'll need either the S351-16 with a 1" shoe or the S390-16 with a 1-1/8" shoe. To determine which of these you need for your repairs, you'll need to confirm your shoe's depth.
You'll need the 1550 stamp option.
