I found (with the help of my kids) a part of a gun today on my parents property that has been in our possession for 40 years. Prior to my parents living there the area was all NJ farm land and God knows what else. Please let me know what you think I may have found. Here come the pics.
The metal appears to be steel and it was found 6/7 inches deep via the use of a Tesoro metal detector with the settings on a high discrepancy mode. Toy or otherwise, I don't know what would cause the end to sever (unevenly) like that. Metal is metal obviously unlike plastic so it didn't snap off
looks like something that once fit on/over a nut. using the bottom left picture, you can see the inside is octagonal. no way a bullet could come through there, and I doubt even a toy gun would have an octagonal inside
It looks like very deep rifling's, which would not be on a modern gun, however some muzzle loading firearms had quite deep cut rifling. However, I'm not satisfied that it's part of a gun. if it was, someone might have sawed the barrel off behind the front sight, but what is the thing opposite the sight. If it was hollow, it could be a ramrod pipe, if it's not hollow that completely rules out gun part in my mind. That leaves the supposed rifling's a spline for fitting on a shaft, possibly of farm machinery, so something would turn without slipping.
