Hello there!
Thanks for reaching out to us. Can you confirm if the top fitting is "winged" like the bottom fitting? Can you also show us a photo of the inside of the metal channel where the innerspring connects to the pulley mechanism? That'd be located in the middle of the balance's channel.

Yes, it's winged at the top. If you click the photos you can see the whole item.
I'll add the other photos now, note the string connecting to the spring snapped in the middle.

Thank you kindly! Based on what I see here, the S380-18 and S385-18 are my suggestions. The best match depends on the depth of the bottom fitting so you'll have to measure as shown below. You can also select the 1730 stamp option for your replacements.

Comparison of the S378, S380 and S385 balance shoes.
