The box is beat up, worn and may have been on fire at one time but it has been reserved in a nice coat of polyurethane for further wear.  It is solid wood with metal reinforcements and measures about 12" x 18" and stands 11" tall. It has a chunk of wood missing on the front bottom left at the bottom which looks deliberate so I'm not sure if it's breakage or normal for this piece.  The lid has a pressure latch and can be locked shut.  It's hard to read but the 2 long sides are marked Miller MILWAUKEE. Each small end with the cut handles have some sort of etched round symbol in the upper left corner and is stamped FIFTY.  See calculator to ship this old goodie.
