Hello, David! Coil balances happen to be one of our main specialties, and we ship across the globe so we can hopefully be of assistance to you in this project. Those numbers you provided appear to be associated with a couple different configurations, but the most common appears to be made with our 15-111 pivot shoe, Series 160 coil spring, and 15-150D double spring support. However, this is mostly an educated guess on my part. I would recommend reviewing these parts first just to see if they match up to what's in your window now. If not, photos of the existing balance assembly would allow me to see if we have a better match. |
