Page 206 inspection manhole MTB 3 ... this is a manhole in the center bulkhead of MBT 3 may be you should name it : inspection manhole centerbulkhead MBT 3.
The following pages up to 209 deals with the with the  Q tanks. I guess we have discussed it before, but to me using "negative buoyancy tank"for Q is strange, in fact all the ballasttanks are negative buoyancy tanks when diving. It is a long and difficult word which we never used in RN English. Untertriebzelle is a much better German word for the tank and so is Q for quick diving. As you are quite frequently using, to me, the correct name "Q", I guess you should stick to the one and same word in your book. Another word you are frequently using in the following pages concerning the periscope is "wench". I am not familiar with this word, as we in RN English use "Winch". Is it a US word?
I have looked so far through all the pages up to 320 apart from the torpedo pages and have so far not any remarks.

Hello Mr. Tore,

Thank you for the excellent review work...  For my part, my spelling error was really funny and really stupid!

"Winch" is a mechanical device; as you know...

"Wench" is what pirates called women with loose morals...

and that was not picked up with MS Word Spell or Grammar Check!!!

Regards,

I see, I have spent quite a few years in Caribbean waters but never met a wench, put it in your Skizzenbuch dictionary together with Analassen.

Hello Mr. Tore,


Page 337, item 3 on the u-historia drawing is a "Ventilation Pipe" correct?

Absolutely, 3 is the port ventilaton pipe. Below I have made an image showing the two ducts stb and port.

Hello Mr. Tore,


When U-995 was caught in the North Sea gale and damaged in 1953; were the emergency shut-off valves used because of damage to the air trunks outside of the pressure hull?

The damage was primarely done to the casing and the sturdy pipings and ducts inside the casing were intact.

Hello Mr. Tore,


The photo I had of under the deck has the common trunk missing for MBT 2 and MBT 4...  Was that a result of the storm damage?  If so, then the emergency shut-off valves would need to be used...

There are several images of U 995 repairing the casing, however these are photos of the renovation of the museum U 995 end of the 60 ties in Kiel when they removed practically all the pipings and ducts inside the casing prior to making the museum boat. In 1953 after the severe casing damage we ended up in Londonderry and got a temporarly repair carried out on the casing alongside a RN submarine repairship where upon we were able to take part in an execise using the MBT 3. I don`t think we ever took a picture of the damage. Coming home they evaluated the damage with regards to the permanent repaircost and came to the conclusion that a permanent repair would be worth while after all.
 Down below is a photo of the renovation of the U 995 in Kiel around 69-70, as you see they pretty much cleaned out everything inside the casing. I guess your photo is from this renovation.

Hello Mr. Tore,


I assume you meant... "a permanent repair would NOT be worthwhile after all."

Hello Mr. Tore and Maciek,

I believe I have completed the MS Word Master Vision (spelling and grammar check, and art lay-out) of Skizzenbuch 11 x 17 - M for Schiffer Publishing.  This version is a guideline for what the lay-out for the book should look like as proposed by me.  The next phase would be to do the layout for the publishing printer which is so different and special character based.

However, I still retain the option to change the Master if there are still corrections to be made.

I have uploaded the latest version of "Skizzenbuch 11 x 17 - M" to dropbox...

Again, I really appreciate all of your help with this project, and I could not have done it without your help!

Kind regards,
Don_

No Don, the damage was that big that voices were raised to scrap the submarine, but after a thorough evaluation  the navy decided to carry out permanent extensive repairs. but after this event she was taken out of service and became later a training submarine and the active crew including me got another VIIC, KNM Kya ex U 926 being only sligthly different from the VIIC/41.

Still some 50-60 pages to double check, however my computer is about to give up, it looks as if some of the prossesors are gone, so I have ordered a new one which shall be ready next week.
