Single arm truth operator used on 14" left side casement of Marvin bay window (early 1990's)

Hello - This single arm operator had the worm gear push out. I cannot find a similar single arm operator anywhere.
DO YOU HAVE THE EXACT REPLACEMENT PART OR ONLY SOMETHING CLOSE?

It looks exactly like the image posted back in august 12, 2014 in which Tom from SWISCO responded:

"August 12, 2014
I would start by looking at our 39-035 and 39-036. These appear similar, but check them out and see what you think."

Thank you Jody - I have ordered the 39-035 and will provide feedback on how this replacement model functions in the window.
