Trying to identify correct window crank

A contractor from Berkeley says:
Hello, our carpenter is having a hard time finding the correct crank for an old window. The stamp on the crank has the name Anderson on it. Any ideas about what he might be looking for or suggestions to find the right part?

Hey there, thanks for writing in! Your casement operators appear to be an older version of the Andersen Straight Arm Operator, part 39-095. Carefully look over the dimensions and compare them to your operator to confirm if this is the right replacement. The opposite version is part 39-094.

The compatible cover is part 39-154. The compatible crank handle is part 39-286.
