Thanks for posting. This looks like either our S351-28 or S390-28. The only difference between these two balances is the 'depth', or heel-to-toe measurement, of the bottom nylon shoe, so compare both with your old hardware to see what matches best. If the depth is just 1", then you'll need our Series 351. Your stamp code indicates you'll need a stamp option of 2730. Let me know if you have any other questions. |
