[NZSnowman]

Hello All

I would to introduce myself. I'm Simon Morris from New Zealand. For the last 10 months I have been drawing a 1:60 scale of a general VIIC/41. Durying this time a few quection pop up about the VIIC/41. I am hope that you guys can help my with a few 

Here is my first question.
I am looking for the other none water markings, I have seem to found mark II, III & V. I am looking for mark I & IV. I am thinking they are both on the port side of the boat, but i can not found them in the pictures i have of U-995. Does anyone found where they are?

Hi NZ, this post is quite a bit later but can you please if possible redownload the schematics, because it is now an INVALID FILE?
Thank you very much: Marcus Silva

A small update today for the outlets valves for Diving Tank 3. I found this picture from http://www.u-boot-zentrale.de/eng/tower.htm with a wire net to protect against foreign bodies entering the tank.

Here two small updates for this post.

The vent in the picture (left) of U-249, I mislabel. It should read MB & RFO Tank 2 and 4, not MB Tank 3

So now for the drawing above the vents MB Tank 3 (left) & MB & RFO Tank 2 and 4 (right).

Another small update for this post, my original drawing (above) shows a wire net over MB Tank 3 (left), this vent shouldn't have a wire net over it.

Excuse my ignorance but what are those valves for?

[NZSnowman]

The MB Tank 3 (picture left) lets the air out for the main driving tank so the U-boat are dive.

The MB & RFO Tank 2 and 4 (picture right) let the air out for the tanks 2 & 4 so the U-boat are dive and trim itself.

I am STILL waiting for the full size boat to be built from these...

Exhaust Gas Blowing System

The exhaust gas blow system used exhaust gas from the main engines to assist with blowing the tanks to raise the U-boat. A pipe extending forward from the main engine exhaust valves, to led forward to a manifold located over the control room. From the manifold, smaller pipes runs to 8 tanks around the u-boat. The eight associated valves in the manifold were operable from within the control room.

WOW! You are now an expert in all this piping. And really nice shading on the center pipe, as it goes from blocked/covered ti more opne. Very well done.

I can say,..this Thread is a perfect Help for me and let me see a lot what i didnt know!:).

Really good Work!!!

(sorry about my english:\)

[Rokket]

That's what we're here for, Nevermind (and your English is fine). NZSnowman has done a brilliant job on these drawings - not just the dwgs themsleves, but translating photos to diagrams.

Does anyone know if the German's keep the mounting for the forward deck gun (8.8cm) on the late war Type VIIC or on the Types VIIC'41? Or did they completely remove the whole mount under the deck?

Thanks, Simon. 

[Rokket]

hmmm, don't know. My gut is the mount stayed an just the gun lifted off. That's pretty standard for most of the removable stuff.

[NZSnowman]

I think you are right, that they leave the mounting under the deck. As the German's would never know for sure if they would not reuse it late in the war, if things got better.
