A few answers -
Links to some of the pictures inside the lid:
1) M1C and M1D GARANDS:

For the left-most picture, I used these two rifles, plus another plain Garand, plus the small soldier from the next link.
2) 12 POSTERS AND SMALL SOLDIER (as above):

then click on the bullet that says 'Oorlog & Garand Posters', then click on the poster "My M-1 does My Talking", and you should get the 12 posters.
3) Plans, dimensions, etc. What I have is my design, and since I knew what how I was going to build it, all I had to draw was a simple but accurate cross-sectional view, which I did with DesignCAD. It shows the 'assembly' of the lid, the hidden barrel hinges, the acrylic retention atop the case frame, and the hollow bottom construction interlocking edge and keyed locks. If I can figure out how to post this, I will do so. The case consists of some 30 wooden pieces, not counting the inlay, plus the hardware.
4) I am seriously looking at making several more cases, and perhaps different styles. (Not everyone may need the feature that renders the contents inaccessible except through the lockable bottom.) I believe I have found the means to duplicate the inlays reliably and perhaps even affordably.
I'll keep you posted.
