Hello,

I suspect that you may have either our S351-27, with a 15-002 bottom attachment, or S390-27, with a 15-001 bottom attachment but you'll need to remove an undamaged balance from another window to confirm since the bottom fitting in your photo is broken.

Once you have an intact balance handy, take a look at the image below to determine which balance you'll need. You'll also need a 2630 spring strength option for your replacement balances. Thank you!
