Spiral balance and bracket assistance

Question

Wanted to know if you can help me determine what balance I need. I believe it is a 9/16 but it does not have a color. Attached is a picture and it will also need the little bracket to attachéd it to none tilt window.

I recognize this old balance. These haven't been made in a long time, but you can use our Series 500 as a replacement, along with our 17-012 bottom bracket (sold separately).

Since your old balance doesn't have a tip color, you'll need to weigh your sash on a scale to confirm the best choice for the Series 500. We have a chart on each balance's store page that tells you how much weight each tip color supports.
