The balances are 30 inches long (metal section) and have the code 2910Y stamped into them (see photo).

Hello,

It looks like you have either our S351-30, with a 15-002 bottom attachment, or S390-30, 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 2910 spring strength option for your replacement balances. Thank you!
