Hello, It does look like you have either our S351-33, with a 15-002 bottom attachment, or S390-33, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need base don the depth of your bottom attachment. You'll also need 3250 spring strength options for your replacement balance based on your stamp number. Choose the spring strength option based on the stamp on your balance. Comparison of the S351 and S390 balance shoes.
