Casement operator part

A quick learner from USA says:

I am looking to get some replacement window casement operators. Would you be able to help me identify the part I need?

Attached are the pictures.

Thank you for your time and effort.

I believe the operator you show in these picture sis a match for our 39-253L and 39-253R. Let me know if you agree.
