Replacement operator

Hi, need some help looking for a replacement part for a casement window crank. Please see the pictures below to see that the internal screw has been stripped. Unfortunately I do not know the brand of the crank.

Can you give me a clearer picture of the entire operator, including the link arm? From there, we'll do our best to find a match.

This looks possibly like the 39-171. Look over the dimensions and see if you agree.

Yes!! That's it, measurements line up. Great I'm going to order it. Thank you.
