Alpine Window Missing Balances

Question

I bought a home that has a window without any channel balances in place, which makes it hard to find a replacement! Of course, it's the only window of its kind of the house, too. It's a 24" Alpine single-hung window, and the sash weighs about 16 pounds. There is a serial number-looking code on it that reads AP-1 ASTM E 774 CL A ALI. I'd love any guidance on a possible replacement!

This is indeed a tricky situation, but we still may be able to help. First off, are there any identical-sized windows in the house with the balances still intact? If so, going off them would probably be a safe bet. If not, is there at least a similar window in the house that still has the balances? If so, please remove them and show us the fittings on either end--that will at least help us narrow down the kind of balances you're working with. The Alpine brand isn't associated with any specific kind of channel balance, so I'm afraid we can't go off manufacturer information alone.

Next, is this a non-tilt window (i.e. it can't be tilted in for cleaning)? If so, please tell me the height of visible glass in the window sash. Also, please give me the exact weight of the window sash. This needs to be precise as possible. That, along with the other information asked for, would be a huge help.
