Hoping to Buy this Channel Balance?

Thanks for posting. That code actually refers to the strength of the spring inside the balance. The balance's identity is determined by the nylon fittings. Take a look at our S380-35 or S385-35. The only difference between these two balances is the 'depth' of the bottom nylon shoe, or what can be thought of as the 'heel-to-toe' measurement, so compare both with your old hardware to see what matches best. You will need a stamp option of 3440.
