Welcome to Swisco.com. Your balance looks close to both our S351-24 and S390-24. The only difference between these two parts lie within the bottom balance shoe. For the Series 351, the bottom shoe's depth measures 1" and for the Series 390, it measures 1-1/8". You will need to measure the depth of your shoe, like in the diagram below to determine which balance will work. For whichever one you will choose will use a 2340 option in place of your stamping of "23D."
