Andersen awning window crank, window approx install 2017

Thanks for writing in. Hm, this operator is a little unusual and we don't have an exact replacement. Take a look at our 39-083. See if the dimensions match; if so, you may be able to use it as a replacement. You'd need a new crank handle as well--see our 39-114L. 

I'm afraid we've never been able to find a good match for this operator, even after all these years. Looking back on Bob's response, I'm not at all optimistic that our 39-083 can replace it. If it could, then it would require significant adaptation of the window sill. I wouldn't try it without professional help, and even then it's not guaranteed.
