WW2 Soviet naval sea mine, this mine is fully 100% deactivated, the shell is still absolutely solid, no rust holes, just surface rust with natural patina, still holding some original paint in places. An awesome piece history for any military collector, boat owner, garden art, bar or restaurant, man cave. I did have plans to restore the look back to original, fabricating the contact horns and caps. Also would make an awesome BBQ or smoker. This particular mine was launched into the Baltic sea during WW2 by the Soviet navy and finally washed up on a beach in Estonia, where it was made safe. Please feel free to contact for further details or photos.
