Unsure of window part

Thanks for posting! I am confident that we have replacement balances that might work for you, however, I'll need to see a photo of an undamaged balance to confirm. 

I am assuming that these are likely a tilt-window channel balance, although I could be wrong. If my assumption is correct, I'll need to see a photo of the bottom attachment of the balance. This is likely still in the window channel and could be connected to the bottom of the window.

Let me know if you have any questions.
