jalousie window likely stripped crank

Hello there. I believe we can help, but if the crank handle had stripped, then the whole mechanism should be replaced. We can likely provide a new operator, but I need to see the entire mechanism, including the link arm, out of the window. Specifically, I need a view of the rear of the operator to see the hole pattern on the top and bottom tabs, as well as a view of the link arm with the hole at the end. From there I'll do my best to find what you need. 

Thanks for these photos. Start by reviewing our 39-025, 39-061, or 39-278. Look over all the pictures and dimensions of these operators and see which of these matches what you need.
