This Biltbest window, along with all of its hardware, has been discontinued and is no longer available. However, take a look at our 39-013 operator, along with the 39-114L handle and 39-533 track. Compare the dimensions of the 39-013 with your existing operator and see if you could possibly retrofit this to work in your window. You may need to cut your existing sill cover to accept it, or even have a new one fabricated. I'm not sure. See what you think!
