Hello, thank you for posting!

With this combination of attachments, you could have either an S380 or S385 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. The length of the metal channel should measure 18" and you will need a stamp option of 1730.

Comparison of the S378, S380 and S385 balance shoes.

Please let me know if you have any questions. We do recommend replacing both sides at once due to pairing a new balance with an old one would cause the new balance to wear out faster.
