Shoe and matching balance 24"

Thanks for posting. This pivot shoe might be our 15-129, but I can't be certain without knowing the dimensions. You will need to remove it from the window and measure the width and thickness to see if it matches the 15-129. If it differs in any way, let us know how. A wide variety of different types of balances, with different sizes and calibrations, could work with this pivot shoe. There's no way I can narrow down what balance you need from the shoe alone. You will need to show us one of the original balances. The length of the balance, as well as pictures of any attachments and stamp codes, would be most useful. Many thanks.
