It may be the 58-021, 58-042, 58-045, 58-128 or 58-158.
There is a seal in the center that I can see and similar to these models.
Do you know what the standard size for these are used on the windows?
Thank you,
Henry

Hey, Henry. The wool pile in your photo looks closer to our 58-045. Take a look and compare it to yours.
