marvin casement window dual arm crank replacement

A quick learner from williamsburg, va says:
I need replacement crank assembly for my marvin casement window.
The spread of the arms when closed is approx 23".
The crank is in the center of the window at the bottom.
The crank doesn't close the window, instead the handle threads itself out of the housing
