Well Jeff I tried to find some pictures, but guess it's top secret or something. Those look like the crimpers we used to splice the Hardened Intersite Cable for the systems in the Air Force. It was a large scotch lock type connector (not sure who actually made them) and you crimped a full pair at a time, this was 16 gauge cable with multiple armored layers and a pressure jacket. I'm 95% sure that's what they are, don't know about Bell System being stamped on them either, it's been awhile back.
