Inert, WWII-era, Hungarian 36M "Vecsey" Offensive Hand Grenade with traces of the original red stripes.
The leather safety tag is marked "G"
The following is copied from LexPev:
This offensive grenade was made of this sheet steel and had an impact fuze.
After pulling the safety, the top of the grenade would unscrew during flight, releasing the strikerpin that would go in position.
On impact, the striker pin was driven into the primer and the grenade would detonate immediately.
If the grenade failed to explode, the mechanism had a function to block the strikerpin so it couldn't reach the primer anymore.
Live grenades are marked with three red rings around the body, the practice grenade had three blue bands around the body.
