Hello, I have a house with many of these operators that need to be replaced. Your help identifying the correct part is greatly appreciated. There is no brand name or info anywhere to be found on the window. The photos attached show what I can see and measurements are there. Please let me know if you need anything else. Thanks, Bob

Many thanks for writing in! Take a look at the 39-054 right hand operator. See if this matches up to yours. Also look at the related hardware and video associated on this page.
