Ok, I work in a auto restoration shop located on a farm. The land owner was mowing hay Friday and ran over this before he saw it. To me, it looks like a detonator, but as to what type of ordinance it attaches to, I have absolutely no clue. And I may be wrong about the detonator bit to. I would like to know what it is and what it goes on. It still had the plastic plug in the open end and you could see eight electrical pins with letters and numbers beside them up inside the piece. And it is about 10" in height and 2.5" in diameter. So, with out further delay, here are some photos. Oh, and Homeland security now has the piece in question.
