Hi Steve, thank you for posting,
For a compatible handle to the 39-139 operator, please see the 39-114L or the 39-205 folding handle.
For the screen clips, I believe you may have style like the 70-28, 70-028A or 70-132. Compare the dimensions to your original to see if one of these matches up.
For installation screws, we would recommend taking your originals to a local hardware store to match up, as the size/length can differ per window. Let me know if you have any additional questions!
