Hello,
Based on your stamp, I suspect that you have either our S351-22, with a 15-002 bottom attachment, or S390-22, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need.
If one of these balances are a match, you'll also need a 2140 spring strength option for your replacement balances. We'd like to see a photo of your balance removed from the window to confirm. Thank you!
