Anderson Awning window

A home owner from Providence, RI says:
I can not find any marking to get a replacement. I assume I have to replace the entire mechanism given the post is broken. Please tell me what parts I need to order.

Thanks for posting. Your crank handle could be our 39-226, based on your picture. If you do need an entirely new operator, however, then we will need to see the complete mechanism out of the window.
