Viking window channel balancers

Question

I have about 30 windows like this that some work and some need ne balancers. Hoping you can help me figure out what I need so I can order replacement as needed.
The window I am working on now is missing all the wardwear in the channel. The picture is from a different window in the house that looks to have a broken end. the window with no parts, is 34 in by 18 in alumin. the window is bigger but the part of the window that goes up and down is only 18 inches. house built in 1985

I have known most Viking windows such as yours use our Series 395 channel balance with our 19-005 top and our 15-001 (1-1/8" depth) bottom balance shoe attached. I highly recommend you make comparisons between your balance and ours. I also couldn't read the spring weight number on your old balance. I would like for you to please measure the metal channel length and provide us the four digit number stamped on the balance.

For the window missing the balances, may you provide us the visible width by height of the glass you see along with the weight of your window sash?
