Hi there!

Thank you for reaching out to us. Your balance looks like a match for the S351-23 and S390-23. The important difference is the depth of the bottom shoe, so you'll have to measure as shown below.

You will also need to weigh the window sash on a scale to determine the correct stamp option since the old one doesn't match any of our options. There's a chart under the S351-23 and S390-23 product descriptions that you can use as a reference.

Please let us know if you have any questions. 

Comparison of the S351 and S390 balance shoes.

In that case, see the S390-23 with the 2230 stamp option. A pair of balances with this stamp will support a sash weighing 12 to 19 pounds.
