These photos will be my reference points, no cleaning, just out of the box detailed photos I can later use for the restoration. This is the 911R, the pilot's racing bucket seat!

Notice the contrast between the 'hand' vs. the 'machine' stitching https://pbase.com/9146gt/image/137114511 of the seat, not to mention the interesting wood insert found here https://pbase.com/9146gt/image/137114493. A closer look of the area https://pbase.com/9146gt/image/137114501.

Here is another area that I find a bit different than other like-seats I've seen, it has two folds of the material on the sides https://pbase.com/9146gt/image/137114531. Some of these difference are 'news to me'!
