Missing channel balance & window model

Question

Hi,
We have a window which slides up, I believe it?s a double pane vinyl window. The entire window opening is
34 1/4? (L) x 22 1/4? (W)
The lower half of the window is
19 3/4? (L) x 16? (W)

I was unable to find a window sticker or marking with the make or model#.

Unfortunately, without one of the original balances to use as a reference, it will be next to impossible to know what to recommend. We could guess, but I cannot guarantee our recommendations will be accurate. Do you have a similar window in the house that may use the same hardware? That's the best case scenario. We could use the balances in that window as a reference. If not, we'll be forced to guess.

Whether or not we have a reference, can you also tell me the height of the visible glass for the sash that needs balances? Can you also tell me how much it weighs?
