Thanks for reaching out to us! I am confident we can supply you with a replacement for your existing balances but I'll need to confirm a few details to determine the correct replacement.

To start, may I see a photo of the spring and pulley system in the center of the balance? This is where the string and balance spring meet.

I'll also need to know the dimensions for the depth of your bottom shoe; the front to back measurement. This measurement should either be 1" or 1-1/8".

Thanks for the photos. I'm sorry to say that I cannot determine the measurement based on the photo you've provided. It is often difficult to read dimensions from the photos and the ruler is at an angle.

Your balance looks like it could be either the S351-29 with a 1" shoe depth or the S390-29 with a 1-1/8" shoe depth. Take a look at the diagram below for reference.

You'll need to select the 2840 stamp option.
