Window crank needs replacing

A home owner from Westerville, Ohio says:

I need to replace the crank operator on 3 windows. It appears that they may be stripped, as the handle no longer turns the crank to open/close the windows. I have included several pictures to assist in identifying the replacement parts needed.

Thank you for your help.

Please start with our 39-031 and 39-032. I think these match your hardware pretty well, but let me know what you think.
