Hello! Looks like you have wool pile. We carry a ton of different sizes, but I can't make out what you need from these photos. You will need to remove a piece of your original, measure it as carefully as you can, then review the list of sizes we carry here.
Note that wool pile sizes tend to be very specific, and you also have to account for wear; in other words, the height might be a little less now than it used to be when it was brand new. These are things you have to account for when measuring. if you have a pair of calipers, now's the time to use them. A tape measure may be insufficient. Otherwise you just have to use your best judgement.
I'm afraid that this does not narrow down the list of possibilities. Your only option is to remove the original and measure it as best as you can. There is no stamp or marking on the window that will tell you what size you need, unfortunately.
