Some neat items from an estate...PIC HEAVY

What you could do is take it out and tape it to a stake and use a line to pull the pin. I'd just pull it and toss it around a tree or building corner so it blows on the other side, there can be shrapnel from the blasting cap. That is providing the striker is still cocked. Also the bobby trap switches you have contain live primers. Those are like a small rifle primer or small pistol mag primer, maybe shotgun primer depending on what exactly they are. Those can launch an anvil like a small projectile.
