Old Casement window operator

A quick learner from PA says:

We have an old casement window. I don't know the manufacturer (hence my reason for contacting you). Do any of you recognize it? There's only one identifying mark stamped on the short portion of the split arm. The long portion of the arm is about 5 inches. Sorry I forgot to measure the mounting hole distances. If you don't know of anything that would fit then I'll just use a manual rod type until I get a new window. Be assured that any help is appreciated.

It might be a TAFCO WINDOW from Home Depot.

Hello,

We offer the video below, which shows the parts that we recommend to replace the discontinued GU operator shown in your photos. Take a look and let us know if you have any other questions. Thank you!

Ok got it the operator is discontinued. My window is the opposite of that shown in the video so I think I'll need operator 39-315 in white, stud bracket 39-513, detach clip 39-105, and finally crank handle 39-114L in white. Does that sound right? Meaning did I forget anything? I know that I'll also need screws from my local HW store. Thanks for your help
