Thank you for posting on the discussion board and submitting your photos to us, Don.
From the images you've submitted so far, it looks like you have awning windows that open up from the bottom. However, we will need to see photos of the complete operator with the arm and the clip on the end of the arm in order to accurately identify the operator.
Don, thank you for your patience. We are still in the process of researching possible replacement operators.
I will post an update on the discussion board as more information becomes available.
Don, we've come to discover this operator has been discontinued and is no longer available.
I am sorry we cannot supply this part to you.
Dave and Mike,
Thanks so much for your help. I guess I will have to get creative.
Don
