To help settle any problems with the pictures that were used, this case was built for mikesky. These are my pictures I sent to Mike when I originally built the case.
If it's one of Jack's cases it's made using Wicket and Craig veg tanned leather. I don't believe Jack would ever use anything other than leather, he was very proud of his work and wouldn't have done anything to jeopardise his reputation.
I don't think most people have any idea how long it takes to build a case, lots of steps and lots of waiting on things to dry are involved. I had guys think it only took two days to build a fully carved case, it takes that long to draw the pattern.
