Hello,

It looks like you have either our S351, with a 15-002 bottom attachment, or S390, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need to locate the stamps on both metal channels to choose the corresponding spring strength options for your replacement balances. Thank you!

Stamps on channels as follows
On the 17 in stamp reads 1640
On the 23 in stamp reads 2230

I don't know which option to use

Thank you

Once you choose between the S351 and S390 by following the diagram I sent you, you'll use a 1640 strength option for your 17" balance and a 2230 strength option for the 23" balance.
