Went out this weekednd to a construction site/an abandon property slated for development and found these cool pieces of artillery shell. The fragmented remains of an exploded shell are most likely, given where I found them,from battle of First Bull Run. Amazing that this one little site surrounded by numerous houses would yield such things. I can only imagine what cool artifacts were lost once the houses were built. In addition to the fragments I found a few bullets and a nose piece to an enfield rifle.
