Welcome to SWISCO. Your balance closely resembles both our S351-25 and S390-25. The only difference between these two balances is the depth measurement of the bottom balance shoe. You will need to measure the depth of your bottom shoe, like in the diagram below, to determine which balance will make the better match. Whichever one chosen will go with a 2420 option.
