Operator Replacement

A home owner from USA says:
Looking to replace 3 Operators for my louvered windows on sun room porch. Unsure what model matches as I have been unable to find any markings on existing operator or window to identify manufacturer. I have attached photos and am hoping you can advise.

Please see our 39-084 operator. This looks like it could be a match, but see what you think.
