Parts missing on Anderson windowalls crank

Hello! This operator looks like it could be a match for either our 39-094 or 39-150 operator. These are both Andersen brand parts and are nearly identical in every respect except for arm length. That's the first thing you should check to determine the proper replacement. I'll share dimensions for each product below that you can use as a reference.
