Window cranks and hardware

A quick learner says:
I am trying to make sure I have the correct hands and hardware to fix my windows. I have attached 3 pictures showing the setup I have.

I would like to replace the crank and the casing. The handle just comes out and I am assuming its not supposed to do that. I think I may need the arm as well.

My window opens out. Each handle is in a different place. Do I need the same set up? just in right or left handed placement.

Hello!

Thank you for your patience during this busy season of ours. Unfortunately, it appears your operator is stripped so you'll need a new one. I recommend our 39-330 along with the 39-205 folding handle. Review our specifications and see what you think.
