Where online can I get a disarmed grenade?

I like buying odd things and things that just peak my interest, and for a long time I’ve wanted one but I’m having trouble finding a place online to get one.

I want to get a real, disarmed grenade, with the pin and lever all working as you’d think they would, without of course exploding. It would make a neato prop, being able to pull the pin and have the lever flip up and all. It would also be cool because since you can unscrew the top you could keep stuff in there or something.

Anyways, where can I get one? All the ones I can find are “dummy” ones which are basically just paperweights. I’m looking for a pineapple styled one. I did find this but I need to ask if it functions like this.
