Stripped Crank Shaft

A quick learner from Buffalo, NY says:
I haven't had a chance to remove this yet, but can do that if that helps better identify the part. It is for a small bathroom window. It is stripped and no longer operates.

I am afraid when the entire handle and gear is stripped, it means the entire operator must be replaced. We can certainly help with this, but we need to see the entire operator, including the link arm(s). From there we'll narrow down what you might need.

Thank you so much for taking a look at this. I struggled to get the entire operator off ( would not come loose after unscrewing), but am going to research and give it another go in a few days. Attached is the number on the two arms - will this be sufficient to identify the new part?

These numbers are associated with a few different parts. If you could just show me the operator base and arms from a bird's eye view, with the window open, that honestly should suffice.

I got it removed! Here are the pictures

Great! I believe this is our 39-330. Take a look and see if you concur.
