Bren Transit Case

[derk derin]

Here is a shot of my transit case with the items placed in there cubby holes.The only spot I don't know what goes there is in the middle section,there is a square area with 2 strips of wood screwed to the bottom and a strip of wood screwed to the front section of the box that hinges sideways to hold the item in place securely.The square area measures 3 1/4'' x 3 1/4'' x 3 1/4'' high.Any ideas?






Here are all 3 boxes,the bottom box is a MK 2 which is 1'' longer than the MK 1 boxes to compensate for the longer butt stock strap of the MK 2.
