Ammunitions passing hatch inside conning tower

[bianco64squalo]

Hi eveybody,
someone knows is the hatch through ammunitions were passed from inside conning tower to deck ( see in the posted photo ) is that one circled in red in the second photo ? Or is it the oval hole visible on third photo, probably near the access to conning tower hatch ?
In any case, is the someone who has some more detailed photos ?
Thanks in advance.

I just remember fig 2 is high pressure air.

I am not sure why, however, the other boats remove a whole section of a hatch
