Opposite hand for Window Crank?

A quick learner from Kansas says:
Hello! I ordered window dyad crank 5" in white part 39-089 and it seems that I need the opposite one. Can you confirm and suggest the right part number? The picture has the old and new one included. Thank you!

Sorry to hear it was the wrong version. The opposite handed version you are looking for is the 39-090. Take a look and see what you think!

Facing the casement window from interior, which crank is for left window 39-090 or 39-089?
