Hello there!

Your pivot shoe reminds me of our 15-129 which is often used with the Series 770 channel balance. You'll need to remove an undamaged balance and pivot shoe to compare our specifications to yours in order to confirm if this is what you have. You'll also need the 28C spring strength option for your balances.
