Hello, thank you for posting!
It looks like you have either our S351-17, with a 15-002 bottom attachment, or S390-17, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need.
Comparison of the S351 and S390 balance shoes.
Please confirm that the length of your balance is 17" and stamp option needed with be 1620. Please let me know if you have any questions!
