U297. Among the first of the VIIC/41s. Sunk on her first patrol.

On another note, I've seen pics of many builders opening up these floods and replacing them with louvres. Is there any evidence that this was done to WWII uboats? Considering how they were used, I cannot imagine this being the case.

Did they slide, hinged at the top or bottom, etc.? Are there any decent pics of these vents open? I've seen one shipyard photo with the vents on tank 2 open, but cannot make out any details; and one of a uboat run aground while e
