As if you couldn't tell this is the forward torpedo room. The ladder at the top is to the torpedo loading hatch. If you look on the rail where first bracket on the torpedo. You can see the hand crank to load the torpedo. On the upper left tube (tube 1) you can see the red handle to the outer torpedo room door. On the lower left you can see the false floor (yes it is all a false floor) removed. You can also see the torpedo. Notice the cabinets on the left and the beds on the right. That must have made some people nervous to sleep there.
