Thank You for your reply. An interesting thought. I have not seen anything that shows otherwise

I have found the following in the Design studies type IXC report.

S75-3 area

""The topside torpedo handling gear varies from U.S. practice in several features.  Additional deck arrangements, such as tracks and a dolly, are made necessary by the Germans' extensive use of topside stowage to supplement limited below-decks stowage. ""

I used the word trolley they used dolly in the above.

I posted a pic showing the crew working with a torpedo above deck in another topic. As to there being a dolly being used or ?? I don't know. Finding more info on this subject would be nice. Anyone??

Hi Simon,

I have found an interesting report from a member (Mr. Martin Beisheim) of U-67 (Typ IXC) on the Website of "Deutsches U-Boot-Museum". The letter was written 1985.


Beisheim wrote about the Alberich coating which was applied to U-67. Here is my short summary of this letter with focus on Alberich issues.

]U-67 got the rubber coating in 1941 in Wilhelmshaven (Shipyard: Westwerft) during repairs between trials and war patrol. The boat got a "roof" and "curtains" of canvas to protect the boat from observation. After that kind of mantling the whole outer hull was sandblasted. It was important to got a complete dry working environment Beisheim stated. The crew of U-67 had to stick the tiles to the hull. Shipyard workers and other uboat crew members asked what was going on behind the curtains but Beisheim and his comrades were strictly forbidden to talk about their work. He wrote that the complete outer hull and the diving rudder and rudder were coated with rubber.

He described the glueing of the tiles as following: The tiles were from black rubber with a measurement from 2 x 1 meters and two parted: One part was perforated and stuck on directly on the hull, the second part was a closed rubber tile which covered the first one. Every tile had a thickness of 1–2 millimeters. The perforated tiles had different holes altering in diameter and distance and were related to the thickness of the outer hull. So the pressure hull got a different coating (resp. hole pattern of the tiles) then the diving tanks or the metal sheets of the conning tower for example. The rubber was supplied by IG-Farben, the company sent their own workers to the yard to help and instruct the crew of U-67 during the works. After the rubber tiles were glued to the hull they were pressed with a roller to the sandblasted steel. After the whole boat was glued with rubber, the U-67 was painted grey with a special rubber color.

During the journey from Wilhelmshaven to Kiel the first rubber tiles detached from the hull. When U-67 arrived in Kiel it revealed that more then 20% of the rubber coating had to be replaced. So the uboat was covered again with canvas for dryness matters and curious views protection. Beisheim wrote that the replacement was a "nasty work". Shipyard worker helped the crew of U-67 and galvanized iron ledges were fitted at the tiles seams, they had to drill and to tap threads in the hull. When the job was completed U-67 was relocated to Apenrade (Denmark). The research vessel "Strahl" did some testings with radar reflections in Denmark, the result was that the absorption of ASDIC impulse was not totally ensured. The tests were continued in Norway (near by Trondheim) after U-67 was again relocated. Gradually more and more rubber tiles detached during the test phase because of the stream during cruising. The crew began to cut of the loose tiles. Before U-67 started the Atlantic war patrol in 1941 the boat had to visit again a shipyard to dry-dock (this time in Bergen/Norway) and removed all loose tiles mainly from the hull under the waterline because of the rattling noise occurred whilst plunge. A new coating was not scheduled.

In addition Beisheim wrote that he had seen a VIIC boat in Kiel (mid-1942) with a black coating which surface structure was equipped with small knobs, he did not remember the number of that boat but he nicknamed it „schwarzer Streuselkuchen“ („black crumble cake“).

That much to Beisheim and his report.

Some thoughts:
– I suppose Beisheim could not know the difference between synthetic and real rubber so he used „rubber“ to describe the anechoic tiles.
– The different hole patterns oft the tiles depending to steel thickness of the hull seem to be a very complex proposition.
– I think the „black crumble cake“ description is very interesting. I reckon that the „knobs“ were the reversed shape of the well known Alberich tiles (with the hole pattern). Due to material shortage and time savings during idle time it could have been a clever idea, because there is only one tile necessary and not two for coating. What do you think about the „crumble cake“?

Torps were rolled on the rails.

Very unique. Nice job!

 Although an older tool from the 1970's, it still has potential to build into a nice model.  Mostly out of the box with decals from Aero Master for aircraft flown by Hagen Foster in Spring 1945.  After completion, I noticed a few gaps in the canopy fit!  Many thanks for having a look.  Questions and comments are most welcome.

Another vintage kit from Revell.  Scale uncertain, but often reported as 1/69 - seems close to 1/72.  Kit comes with fully detailed interior which I did not use for this build.  All parts required much attention as the tool is very old and worn, but it does build into an impressive model with some tedious effort.  Simple colour scheme is based on poor photo images of a late production A4/V2.  Figures are from the spares bin along with speculative decal markings.  Mounted on a thin wood base with a clear acrylic dust & display cover.  Many thanks for having a look, your questions and comments are always welcome.

Thank you!
We see the pics of the rails all of the time and see the statement about how the trolley was used to move the stored torpedoes around on deck to load into the pressure hull. But I have not seen a pic or diagram or any major info on the trolley. Anyone??
