Thanks for posting. Before I can offer an applicable replacement for your balance, I just need to know a bit more information about your bottom shoe. Please refer to the following chart and pick out your shoe from t he examples given. Please keep in mind that while a fraction of an inch difference may not seem like much, it is in fact vital the operation of your balance. I urge you to get as exact a measurement as possible.

The actual measurement is 1 1/16", and it has wings. I think 15-004 should work. I measured with a 6" scale graduated in 32NDS & 64THS inch. Thanks

Thank you. In that case, please take a look at our S385-30 with a 2950 stamp option and see if that will work for you.
