I don't have that actual bag to compare to and I can't find any others from the same date and plant however, I don't see problems.
Other opinions are certainly welcome.
I wonder whether the differences you're noting in the weave are on 19747 vs. a similar style,
I found this video where the style is the same one and the leather appears thicker and similar to yours.

Hmm. Here's a possibility. Your creed shows the style number as 19747 and the video has the same type of leather.
This listing shows 19747 in the title, but the picture of the creed and the description state the style as 19746. I wonder if that's the difference.
