Final missing details. Again don`t hesitate to ask for more details if needed.

Tore, thank you very much.


Could you help me to decipher some labels, marked with blue ovals?
Here are my few assumptions:
1 - something to connect test gear for G7e torpedoes
4 - heating panel for G7e torpedoes?
5 - something related with gyro-compass?

1. is marked as pruefgerat and connected to the switchpanel for light.
4. is marked as heiss-schaltkasten G7e
5. is marked as  E ? kompass.... Could be light for the gyro.

As to the electric system for the torpedoes you shall find a better quality of the text looking at the fwd. torpedoroom.

Thanks Tore,


and the others marks: 2, 3, 6, 7, 8, 9?

Coming up, harder to decipher, trying photoshop possibilities, but no success yet.

I presume 2 and 3 are the rudders, 6 and 7 are the aft hydroplanes. If you look to the fwd. torpedoroom you shall find the same arrangement for the fwd hydroplanes. One type of the boxes are marked " Endlage...". I  believe the boxes are related to the operation system for hydroplanes and rudders. As you know they are all normally operated electric and having electric repeaters for position indicators as well. I assume the rudders and hydroplanes have main switches as drawn.

9 is hard to decipher. It is a converter for the radiotransmitter, but the text is unreadable for me . I am posting a close up photo may be somebody can decipher the text.

The 8 is a hard nut to crack. Below is a close up photo. I believe the first word is "Heissung..." but I cannot understand this as it is connected up to the aux. switchboard. Neither do I understand the type of switch placed in a wire from the aux switchboard.

Looking at the 5 which I assume is a similar indicator ligth system for the gyro, I believe I might see the letters G7e. Could 8 be indicator lights for the heating of the torpedoes?
Tore

[SnakeDoc]

Tore, thanks.


I think, that 1 is for connecting some equipment for testing electric torpedoes. Why only in aft torpedo room? I have found, that there was low voltage motor testing gear, which consisted of acid-lead battery. I believe, that panel 1 was used to charging this battery.
2 - Endlageschalter - limit switch for electric motor driving main rudder
3 - Wiederstande - starting and breaking resistors for motor
4 - G7e Heizschaltkasten - G7e torpedoes heating panels
 5 - E komassumf (former) - rotary converter for gyro compass
6 - Wiederstande - starting and breaking resistors for aft diving planes motor
 7 - Endlageschalter - limit switch for aft diving planes motor
8 - something related with G7e torpedoes 
9 - Senderum (former) - rotary converter for radio transmitter


I will have more questions, when investigating remaining parts of drawing.

The VIIC s surviving the Deadlight.
As far as I remember as a result of the Yalta conference in February 1945 US, Soviet and UK agreed to destroy the vast German submarine fleet leaving only 10 submarines for each of the three parties for research. The end story of all these 30 submarines is not known to me, but as we had a very close cooperation with British submarine services during the war ( 9Th. Submarine Flotilla) we assisted the RN as to the Deadlight transfer of the some 90 odd German submarines surrendering in Norway. The Norwegian submarine officers in the transfer commission came to the conclusion that some of the submarines were not fit for the transfer and they were temporary "stored" and "forgotten"in Norway.
After the cold war and NATO the transfer of these  submarines to the Norwegian Navy was formalised in 1950. Amongst these submarines were 3 VII Cs : U 324,U 926, U 1202 and one VIIC/41 U 995. U 324 was beyond repair and was used as a "sparepart boat", the reminding boats were included as frontline boats as the K class in the Norwegian Navy, got NATO pennant nos. and names of Norwegian light houses starting with a K. Contrary to what is stated these VII Cs were in the first years front lineboats and not training vessels.
