Awning window operator replacement - Don't know what model or part number it is

Question

All window operator parts function correctly except for the silver ridged round piece (gear maybe?) the handle/crank attaches to (insert screw into crank to attach it). It looks like the part might be stripped. It's the piece the handle turns to make the window crank open.

Thanks!

The silver piece is probably a "worm gear," which is unreplaceable. You need the whole operator mechanism.

We can ID the operator, but we need you to remove this operator from the window entirely and show us a clear photo of the screwhole pattern and operator link arms.
