WW2 submarine interior

Just something different. A world war two submarine.
The pictures were all taken handheld with no tripod and no flash, so they didn't come out too bad.
I did use a high ISO,3200 it helped.
Its amazing to think men went to war in such cramped conditions, you have to turn sideways to pass in the corridors. Especially when you read the depth guage and realise all this activity could be taking place up to 140 feet below the surface of the sea. To me its frightening.
