If you cannot see that the inside of this shell is empty, you have to assume it is live. The side pocket fuzes are very worrying as one is likely to be an anti-tamper fuze, and the other could be a time fuze. One looks intact and the other looks like the top has corroded away. What is certain is that it is an artillery shell big enough to atomise everything within about 100yards, and kill everyone else within 500yards. You need to get it checked and quickly.
