The name of style 9965 wasn't Trail Bag, it was Legacy Small Flap. The Trail Bag was style 9955. Neither of those bags is a Trail Bag, the black one is probably a 9965 although without a creed photo it's hard to be sure. The red one looks older, probably early to mid-1980s. It looks like a Small Shoulder Bag but without measurements I'm not going to speculate.
The two bags in your photo are obviously not the same style bag so the comparisons really don't prove that one or the other is fake. The different color metal zipper pull may be a replacement. What you call a "puffy" hangtag was exactly how the mid-1980s hangtags looked.
You can't compare two different styles. If you need the red bag authenticated please post measurements, also a longer view of the creed that includes the inside pocket especially the top. Thanks!
I'll take more pics in the am. My black is a 9965 small flap. I see that bag called a trail often and the seller told me this was a "trail bag" I expected them to be the same. That's where the comparison came from. When you say top of the inside pocket. .. you want the seam area above the zipper where the back and flap meet?
