Hi Filippo,
No one other help ?
You have asked the question
12 hours ago. I would suggest you more patience.
I'd like to know, exactly, the devices and the shaft passing through all the holes visible on the cap, because I intend to scratchbuild all the connections from the cap to the respective devices....
The description of the attached image:
1. shaft for anchor slipping hook
2. shafts for opening the muzzle doors
3. compressed air lines for launching naval mines
4. compressed air lines for operating the naval mines stop latch
5. pipes for draining the torpedo tubes
6. air lines for venting torpedo tubes
U-Boats not fitted with mines launching gear did not have 3) and 4)
However, U 552 could lay mines from her torpedo tubes (note in this
KTB).
Here another couple of photos.
Some question:
- was the U-Boat in the photo with red signs an U-Boat Type VIIC ?
That's right, it is type VIIC U-Boat.
- the red circled object was present in all U-Boat tubes ?
I do not see any red circled object, you mean red rectangle? If so, this support was present between upper and lower pairs of tubes.
- were the ribs indicated in red present in all U-Boat tubes ?
Yes, the ribs were present in all U-Boat tubes.
