Hello,
It looks like you have either our S351-29, with a 15-002 bottom attachment, or S390-29, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. Based on your 17A stamp, you'll also need a 1710 spring strength option for your replacement balances o support a sash between 5-8 lbs. Thank you!
