Hello there!

Thank you for reaching out to us. Our S351-26 or S390-26 look like a match for what you show here. You'll have to measure as shown in the image below to determine which Series is best. There should also be a stamp on the balance's metal channel that will indicate what spring strength option you'll need to select. 

Comparison of the S351 and S390 balance shoes.
