Hello! With this combination of attachments, you could have either an S380-27 or S385-27 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. It's hard to make out your stamp, but if it reads " 26 5", then you'll need our 2650 stamp option. If you want to be safe, you can always check the balance's stamp on the other side of the window. Comparison of the S380 and S385 balance shoes.

In that case, you will need the 2650 stamp option. It's hard to get accurate measurements from pictures, unfortunately. You will have to use your best judgment and work from there. If you'd like a peace of mind, you can see our return policy here. |
