Decoration F1 russian egg grenade, delaborated.
This is the real deal just without function or hazardous material.
In service since WWII and the most often build handgrenade type worldwide.
Here it comes in unissued condition and oliv finish. Also pin and spring are enclosed, meaning when you pull the splint the handle springs of and the firing pin makes a nice click sound. It is reusable - meaning you can set firing pin and spring in as many tiomes as you like.
Original weight 380g.
