Very good review on your initial experience with HH....glad you are one to just dive in and see for yourself what all the talk is about.
Some of those marks you show, I'm not so sure they are actual range, character, or "spur" marks.....looks like they may have been scuffed up after the tanning process. You have to remember that after these "strips' are cut away from the shell, they are thrown into a heap to be hauled off and sold by the pound...probably not handled with much love.
I get quite the thrill when I get one full of the figuring that you show......try dying it tan or lt. brown, finish in Resoline and watch it really pop out.
Have fun with it.....kinda tough to form/mold to make it look like Kydex.....but on some holster it really does well.
