A very naughty U-Boatman bottle opener and beer bottle.
This piece was made some time in the early fourties, maybe during the "Happy Time" by a Kriegsmariner
I've had this since I was a kid and it still makes me laugh..
Just a pity there isn't any markings or stamps on the metal opener
At least U-Boat Mann is happy
I love these little oddities.
Too me, it brings home the human nature to our hobby
