Hey, thanks for posting. I've narrowed this down to two possible channel balance Series: either our Series 351 or our Series 390 balances.
Now, as you can see, there is only one difference between these two Series, and that is their bottom shoe. The Series 351 uses the 15-002 while the Series 390 uses the 15-001. I can't quite tell what you have based on your pictures, though. Please carefully compare their dimensions to your own hardware and see which is a better match.

THANKS FOR THE QUICK RESPONSE, AS YOU CAN SEE IN THE PICTURE THE BOTTOM SHOE IS BROKEN AND I DO NOT SEE A WAY TO TAKE COMPARE THE DIMENSIONS.
WHAT DO YOU RECOMEND?
THANKS

I'm not sure, there is no other way to determine what shoe you need. Is the other balance in the window broken? Are there any identical windows in the house that might have the same hardware?
