Hi Everyone!
Last week, during my research i found a strange mini mortar tail.If you look closely, you see its looks like the soviet 82mm standart mortar tail.But its not...The outer diameter of the wings is not more than 60mm.So it was a 60mm mortar grenade.Unfortunately the bottom fuse is missing.But i haven't find any clue on the internet that its ever existed at the soviet forces.
The place where I found it, there were german, soviet, hungarian and romanian forces.Thanks a lot!

Also found some of these, on places were Germans fought the British & Americans. Think that it is German, don't know which type exactly however.
