On our last trip i found this item but have no idea what it is. I was thinking about the gun mount on some armored vehicle? However the 4 screw holes i can't figure out. Also on the other side of the item there are 6(3 over and 3 under) "locking devices" or something like that The item is very heavy. About 30-40 Kg i would say.
It would be awesome if we could find out what this mystery item is for
