Hello, It looks like you have either our S351-25, with a 15-002 bottom attachment, or S390-25, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need a 2430 spring strength option for your replacement balances. Thank you!

You'll need to confirm that the measurements match up, but it seems like you would need our S351-25 with a 2430 strength option. You'll just need to confirm that the bottom attachment has the same 1" depth, which we can't confirm based on photos. |
