How old was it? I mean, was the fuse still lit? ;')
As I said, solid-shot. 16 pound, rough-cast iron, with flats & scrapes.
No provenance to it, as it was half buried in an intermittant stream bed that is highly disturbed. One driveway crosses it on one side of where I found it, and another drive crosses on the other side of it, about 25' away.
