I have a few windows that are 30 years old and mechanism doesn't work well. How would I know which one to buy. The number on the window is B25888Y26B-2 if that would help at all. Thanks Ron

Hi there!
We'd be happy to help but we'll need to see a photo of your operator with the window open so that the arms that move the sash are fully visible.
