Anderson window balance: need to determine replacement unit

Question

I need to replace an Anderson window balance (and of course) none of the stamps on my existing balances exactly match up with what I see in your catalog (or at least it's confusing enough that I'm not 100% confident).
Here is everything that is stamped on the existing balances (excluding the Anderson logo and patent info):
On the side where the cord pulls out:
11600-17
B D 16 7#27 2 87
On the side opposite where the cord comes out:
11600-3
Which replacement would I need?
Thank you.

Hello there. The 24-737 should work for you. This will replace old Andersen balances with the stamp '7#27'--this is equivalent to the stamp '727'. This balance is non-handed, meaning it will work for both sides of the window. Let me know if you have further questions.
