What Operator is this?

I'm attempting to determine which operator this is. I was uploading photos of it disassembled, when your site either crashed or refreshed, and deleted them. In case I don't have to disassemble the whole thing again, is there any way to determine which one this is? I believe it's a 39-253LB, but can't be sure since the handle cover doesn't actually come off (looks to be riveted together).

Hello, thank you for posting,
Your operator resembles either the 39-253LB or the 39-438B style. The main difference between the two operators is the guide on the end of the arm.
The 39-253LB uses the detachable 39-529 track slider while the 39-438B uses a slider that is not detachable. Please review the video below for more details.
These operators are compatible with the 39-451 or 39-375 cover and handle depending on style preference.
Review dimensions to confirm a good fit and let us know if you have any additional questions!

Thank you. This appears to be correct. The 39-253LB will be the best fit, but the one I currently have had a cover on it that appears to be riveted on. Is there a replacement for that as well? Or how do I detach it from the current one to put on a new one?
