Balance Replacement

Question

This balance is imprinted 30 C 3.S.I.
The metal case seems to be 31" long. It has string and spring inside with plastic clips on the ends.
I'll looking to purchase 20 of these.

Please help.
Thanks

Thanks for your photos. Based on what I see here, you have either our S351-31 or S390-31, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.
