Casement crank

A quick learner from NY says:
It looks like I need a part similar to The 39 - 097. The broken hardware has a window attachment section that is as long as the arm and this differs from what I see online. I believe these are Pella Windows circa 1985. Can you confirm this is what I'm looking for?
