Hello, I agree that the S500-27 spiral balance and 17-012 bracket are most likely the parts that you need. Since the outer tube of your balance is missing, the S400 is also a contender but since older wood windows are usually on the heavier side, the 5/8" thick S500 would be a better option. Thank you! |

Yes, that is correct. |
