Without having the original balances on hand, it will be very difficult to identify what you have. Do you have an identical window elsewhere in the house that you can use as a reference?

I would advise not ordering anything until you are able to use an older balance as reference. The Series 800 is not very common and is specifically meant for a certain kind of window. That doesn't mean that it's not what you have, but it may be worth holding off until you know for sure.
