Re: Sea mines
Hello Alex,
Your photo shows mine cases of German influence mines of the SMA-type. Such mines were laid by submarines of the type VII D or X B.
Greetings,
Schorschl

Any idea about the images posted on 24-26 Sep ??

Re: Sea mines
Hello Sturm78,
such a friendly invitation is hard to resist.
The first picture in your post from the 24th of September shows a British Mk III (or V). The other mines are imho EMC, because the cylindrical mid-section is clearly visible.
Your picture from the 26th of September shows an EMC-mine, but EMD is also possible.

Re: Sea mines
Hi,
It seems like French mine Sautter-Harlé HS 4 AR, in Polish Navy known under designation: S.M. 5.

Re: Sea mines
Hello Natter,
You have a very interesting list put together. However still some abbreviations were missing and a few subtleties were not correct. I have tried to supplement or correct them.
But for the abbreviation VH I can't find anything. In particular, in the German language, a word like "hoerst" does not exist. Can you tell me where you have found this abbreviation?

Thanks for the supplements - I missed some obvious ones there!Schorschl wrote:You have a very interesting list put together. However still some abbreviations were missing and a few subtleties were not correct. I have tried to supplement or correct them.

I started compiling the list due to not having the answer for the original post earlier in this topic (it's about 1,5 years ago I think), and it's based on a number of different sources (documents). I forgot all about it until I discovered the same question in another forum yesterday (I suspect by the same person), and then I found the list and posted it.
As for the words that don't exist: I suspect there might be speling-errors on either my account, or perhaps from an english/US source document (my german is also virtually useless...). "hoerst" should probably be "hörst" (ie listening). Verzögerung Hörst could probably (?) be translated or interpreted into a sort of "delay for listening", or activation delay (which is the intention described originally, and makes perfect sense for an acoustic mine imo - perhaps they used this to distinguish the mechansims from the similar one in the magnetic mines - ie "V.W.").
I can't say exactly where the specific info was found without starting over looking through it all again, but here is a list of some of my documents on the subject of WW2 mines (I think it's most likely to be found in there, but I have a lot more, including many norwegian manuals/directives):

Re: Sea mines
Thank you for your effort, but these are all the 54-page version that floats around on the net (the full manual is almost 300 pages).LWD wrote:Is this copy complete?

I have made the error of ordering some CD's from "MilSpecManuals" in the past: They put a couple of pdf's that you can find for free almost anywhere on a CD and sell them for $5. Not too expensive maybe, but if you buy more they add up the postage as if they intend to send them separately (which they don't). My advice: Stay away...
Anyway: I have now made contact with someone who have the complete manual, and he will hopefully have it scanned for me soon (I would still like to get in touch with anyone having german WW2 torpedo/mine-related documents for exchange though!)

I don't have anything to add to this (other than my thanks for posting the abbreviations), but I've been editing the diary of a Kriegsmarine R-boat skipper and his narrative on mine-sweeping operations is illuminating.Natter wrote:LWD wrote: (I would still like to get in touch with anyone having german WW2 torpedo/mine-related documents for exchange though!)[/b]
