9 inch casement operator replacement

A quick learner from Seattle, WA says:

My casement operator looks just like your 39-384, including screw spacing, but has a 9 inch arm. It says "STC Dayton OH" inside. Would your 6 inch 39-384 work or is there a 9 inch model available? Thanks.

Also, could this be a Getty operator?

Thank you for your inquiry. I am leaning more towards our 39-044 and 39-045 as possible replacement operators. Carefully look over our measurements listed and let us know if you believe these could be used to repair your window.
