Can anyone please help me identify this grenade? I think it’s from WWII, but can’t find anything that looks like it. The German M-24 is similar but has a flange at the base of the metal part and this grenade does not have such a flange. I can not see very well inside with a flashlight, but the string is attached to something inside and it looks like I can see a bit of copper wire inside. Thanks for the help.
