I found an old kit I had bought a long time ago, back when my hands were too shaky to build these kits with so much detail, I knew what the sub was in better detail thanks to the Battle of the Baltic mod for SH4. I built the kit in all of an hour and a half, to the finished product you see here. I love the instruction manual. The sprue in the cellophane bag was attached to the manual (made of a very rough paper, cardstock almost.) by thread.
I have another one of these, I left it in Illinois, it's a D-class, but I didn't spend as much time and I ruined all the decals.
Either way, enjoy the pics!

me holding the sub, sorry for the blurriness. Hope you get an idea of the scale.
