I'm sorry, but I don't recognize this Series coil balance. I will need some additional information before we can research a replacement.

First, please remove the window sash and take a photo of the pivot lock shoe. In your pictures above, the sash is obscuring important details. I will also need to know the width and thickness of the pivot shoe. These dimensions are essential! Please also take a photo of the bottom pivot bar on the sash. Finally, how is the spring attached to the shoe, and what is the width of the spring?
A home owner from North Bergen, NJ says:
new pictures as requested hopefully this time are the right ones.
the with of the spring is +/- 1/2"

Thank you. For the coil springs, I recommend that you consider our S152-9. This can work for sashes weighing from 17 through 19 pounds. As for the pivot shoe, see if our 15-177 is a good match. The most important dimensions are the width and thickness, so you should triple check those to make sure it matches.
