M24 Potato Masher Question

[MauserKar98k]

Hey guys,
I'm trying to make a replica of a Potato Masher grenade, but I could need some help.

What are the exact dimensions of a M24 Stielhandgranate?

I've been looking all over the internet and I can't find anything other than "over 12 inches long".

Thanks for the help,

is it worth making one? they sell them on ebay very cheap and they look pretty good to the average bystander. Glenn
