I have a broken window casement for a small (maybe 30in Tall and 18in wide) Anderson window. The only number I saw on the window was on the small arm. #1361316

If the cover is the only thing that's broken, just replace the cover. Our 39-154 looks like a good option.
Otherwise, I'd recommend replacing the whole thing with our 39-146 operator. How's that sound?
