Hi- thanks so much for posting! 

I'm going to have you start by looking at our 39-013 and 39-014 casement window operators. Take a look at those and compare them to what you have. It is very important that you confirm size and that the wheel bearing at the end of the arm is the same before you go ahead and purchase this. 

Get back to us if you have any questions.

Tom, the arm on my window has a bend of appx 45 degrees. The length before the bend is about 7 3/4 inches. The new photo shows the arm from the outside looking into the casing.

Can you advise?

Ah, I see what you mean. There does appear to be a bit of an offset near the gear. Does that offset go up, or down? We have two operators in this style with an offset that goes up. See our 39-413 and 39-412. However, they only have 9-1/2" long arms. Could you still get them to work?
