I don't have good feelings about either of them.
Below are two creed and serial combinations from months just a bit before and a bit after the July 1995 C plant serial in your backpack. Compare the "No" especially the length of the underscore line and the font of the N. The genuine ones have serifs, short lines at right angles to the long lines of the letter. Then compare the shape of the 9s, and the length of the dash between the two parts of the serial number. You can also see pressure marks above the top right and left corners of the creed stamp which usually isn't a good sign.
The third picture shows the Classic Backpack, notice the turnlock area especially the shape of the padded area of the leather. That shape should be the same on both the Backpack and the Willis, but neither one matches it.
The Willis doesn't have the right turnlock details for that padded area, and the serial number is fake. I made this note about a year ago in my own personal files and haven't seen any evidence to make me change it:
"H8L- prefixes with US creeds seem to be all fake and H8L- 9927 serials have been found in both fake Willises AND fake backpacks"
There is no solid evidence that the L plant code was used for any US plant in 1998 (although there was a Neo Backpack with an M8L-6205 serial that had an incorrect creed description), and combined with the misshaped padding above the turnlock, I'm sure that the Willis is fake too.
Oh My Goodness, I am so glad I asked. There where little red flags here and there with the more I looked at them. Thank you for taking the time & thought into this for me, Hyacinth. I can't thank you Enough!!!! THANK YOU!
