Couldnt read it, but I had a friend that dug up these things since the 1960s a few he sawed in half and displayed.....he never blew one up, but there was a guy in Georgia that blew his arms off doing the same thing.
If the Army has taught me anything, its to never mess with Unexploded Ordinance..... no matter how old it is, and this is a fine example. Mark it with some white engineers tape and call EOD!!!
