Awning type windows

A home owner from Northbrook, IL says:
I have two windows that need the crank and arm hardware replaced. I have uploaded pictures. There are no numbers or manufacturer's markings . I will also need the appropriate crank handles.
User submitted photos of a window operator.

Looks like you have an older style Andersen awning operator. I believe the newer replacement operator would be the 39-389, along with 39-286 handle. See what you think!
