There are (2) KS-20827 LI. One of them has a lots of stains and name written on it. There is (1) KS-16492 L2. Then there are 3 pieces that have inserts. Finally there are 6 more pieces, which I think are parts of others. I think that the bottom tools, are for an unwrapping drill tool (not included) but I'm not sure. Only the (2) KS-20827 LI are marked Bell System.
