Actually, believe it or not, mine is actually a dark grey, and not black. It photographs VERY dark, darker than the eyes actually percieve the color. If you look to the top right of the case, you can see the grey showing, and that part is more like the color in real life.
I have two weller cases. One is clearly black but its on the small side, say 8 or nine inches wide. The other is the dark grey case here, identical shape to the small one, but about 10-11 inches wide. Is it possible you actually have the smaller case Tim?
