Good morning @oldtimer. Isn't it too cold ? I mean -10 degrees . That's freezing cold. How one can bear this much negative temperature? My best wishes to you, your family and all the people living in the same country as yours. By the way the logo on the submarine, that's of walls I think.. maybe it is known different in your than mine.

Amazing pictures. Keep up the good work. Have a nice day ahead .!!
