It looks like you're having no trouble at all identifying these balances -- or, at least, you're 3 out of 3 in guessing! You're totally right about which balances match up to yours. Unfortunately, we do not have a simple chart to look up Andersen balances.
The best way to identify an Andersen balance by yourself is to find the number on the balance with a # in the middle, and type that number into the search bar on SWISCO.com. The top result will likely be an Andersen balance, and it will be able to replace your old balance.
Just carefully read the description on the item webpage for the balance that comes up. It should say "Can be used to replace balance boxes with the following stamped numbers". It will list the appropriate balances that our part can replace. Make sure the number you pulled off the balance is listed there before you buy it.
