Thanks for posting. It looks like you might have the S351-30 or S390-30. The only difference between these two balances is the 'depth' of the bottom nylon shoe. See below. Measure your old balance's shoe depth to see what matches best. For a stamp option choose 2930.

Comparison of the S351 and S390 balance shoes.
