Fenestra 9" Arm Caement window operator

A handy person from hollywood says:
Attached is my part that the teeth on gear is shot.. I have a 9" arm with 3 1/4" hole spacing on body for screws.

I am trying to confirm that your replacement part is Fenestra, Casement Operator, 9" Product Code: 39-358

If not can you guide me? If so,

Does your part say "Fenestra Detroit " on the top of the body of the part to resemble the original?

Thanks for posting! I agree, our 39-358 looks a lot like your hardware. I can't say if its an exact match, but compare the dimensions we show to your own operator and see how they line up.
