Help replacing window crank

Question

Hi, I'd like help replacing the entire crank system of this casement window, including the cover and handle. I think it is a Jeld-wen but can't be certain, as the elements have nearly destroyed the window's I.D. tag (see photo).  I believe this is a RH crank? Many thanks in advance!

Thanks for posting. This looks like either the 39-253RB or 39-439B. The only difference between these two operators is the appendage at the end of the straight arm. See the video below for an explanation. For either operator, you could use either the 39-376 or 39-452 as a cover and handle, depending on the style you prefer.
