I checked what I have and there are two variations to that box.
One has the dark gray paint, a wide extended lip around both the lid and bottom, wider spacing of the raised lines on the cover and the socket section doesn't have the holes and the sockets and tools were BE series.
The second, which you have, has straight sides[no lip], narrower spacing of the raised lines on the cover and the individual holes for the sockets. This box was painted with the hammered gray, inside and out, and had a paper label [oval with the Craftsman bar through the center] and the sockets and tools were =V= series.
Hope this helps.
