Looks like a practice bomb used by the Air Force from the late 60's early 70's.
BINGO
Below is the text from where I posted it on another forum. The member was retired military. I had no clue what it was until this reply appeared. An extensive search on the web had came up empty.
My son found it in the woods while hunting here in Ohio. We don't have a clue how it got there. He was in the process of moving to anouther home and was going to haul it to the scrap yard with a bunch of other scrap. I seen it and said "no way". so I brought it home as a conversation piece that hangs in my work shop.
{Actually guys it is what is called a practice shape, and was used for bombing practice for the A-4 and A-7 type aircraft that I know of and could have been used by others.
It had a small smoke cartridge in the nose, so that when it hit the ground the chase plane could see where the shape hit in reference to the intended target and they are not at all that dangerous.}
