Sorry for any cross postings, but a colleague posted this image (see link
below) on the NYAC group asking for help identifying it. I'm not sure of
the context, just that "A person in Peekskill found it in their back yard
while digging, do you know what it could be? It has a C on it. A magnet
sticks a bit at the bottom of it."
Thanks for any help.
