Is the head weighted? does it feel like if you threw it, it would actually tumble like a real potato masher?
No point being a practise grenade if it doesn't behave like a real one is it?
If is feels right then theres a chance - a faker wouldn't go to that much trouble IMHO.
Great thinking Dan, not really no it's all wood. Apart from the end actually being bigger it's not weighted. I don't think it's been made with any intention to fool though. It's pretty old, if it's not period I reckon it's a theatre prop.
Here`s one I made on a lathe.......Pete.
