Operator ID Help

A home owner from USA says:

Pictures 1 and 1a: operator with measurements.

Picture 2: Runner which screws into bottom of window

Picture 3: space where arm runs to hook-up with window

Please let me know if you have anything available that would fit my windows. I would be looking for black color or possibly bronze.

Thanks for posting, Ben. This looks to be a very old operator. I don't think we can find an exact match, but I have one idea. Start by looking at our 39-344 operator. Now, this doesn't have the long flat bearing at the end of the arm like yours, but if you replace the track with our 39-504, then you may be okay. That said, due to the age of your old part I cannot guarantee that this will work. Carefully look it over and see what you think.
