For your consideration is a nice Heavy Socket set box. It has the divider inside. The top has an oval with three horizontal lines off from it. There is no writing or Trademarks on box, but it is clearly a heavy quality box. Would be great for any old snap-on or Craftsman set. it measure 15 5/8" the long way. 3 inches front to back, and is 1 3/4" deep on the inside. Inside where you would put the sockets is 11" wide. I would have to guess it was for a 1/2" set. It's made of heavy gauge steel. You'd need a hammer to dent it.
