Sea mines
Re: Sea mines
[quote="MarcinR"]I took this photo of sea mine in Museo Storico Navale in Venice. Any thoughts about what model is it?
Hi MarcinR, I believe it is a German WWI EMA or EMB they were also known as C/12, they were deployed by type UC submarines, there are two more on display one at the Laboe Naval Memorial and one at the Imperial War Museum London. The one you have photographed has gear teeth on two of the uprights which the other two do not.
UC-5 was refloated and put on disply with with a couple of these on the hull.
Hope this helps

Re: Sea mines
FYI: I was just looking through some photos I got a while back from a british contact of mine. They are from the Danish Navy EOD-collection, which includes a complete SMA-system.Conshelf wrote:Unfortunately, my copy is of rather poor quality. Here is an image of the complete system:
The photos are not mine to share, but if you give me your e-mail adress in a PM, I can put you in contact with the owner.

This was used by KdK against the bridges of Nimwegen.Natter wrote:
LIZ = Lichtzündgerät (light-operated (photo-electric) fuze)
The TMB were stored in "Sperrwaffenarsenal Trappenkamp"."TMB mine with water balloon
Mines with buoyancy chambers and towed by swimmers. The charge was 1,220 lb.; two mines might be linked together to double the charge. Fitted either with time fuse up to six days, or photo-electric cell firing."
Are there any informations, about experience whith LIZ in Torpedoes?

Re: Sea mines
Hi, Natter!
I have a new question on the German sea mines. On German diagrams, next to the name of the type of mine, written color. View schema fragment for viewtopic.php?f=49&t=222989/
Color is only near the mines LMB III. There is "green", "blue", "red", "yellow" and "green-blue" colors. There is speculation that the color is associated with the direction of the magnetic field. But part LMB III had an acoustic Fuze, and all the mines BM-1000 was equipped with a magnetic Fuse. Near the names of BM-1000 colors no. What is the meaning of these colors?
Best regards, Igor

Re: Sea mines
There were several optical torpedopistols in development, but none ever fielded. From the top of my head, you have the Pi-S, the Pi-O and "Leuchtfisch" (I have some limited info on this, but not at hand and I'm not able to look for it at the time being).bettika wrote:Are there any informations, about experience whith LIZ in Torpedoes?

Yes, that's on my list of reports in relevance to german development of optical pistols:bettika wrote:more informations could be inside https://catalog.archives.gov/id/4346374From the top of my head, you have the Pi-S, the Pi-O and "Leuchtfisch"

WW2 optical pistols are not mentioned in Bundesmarine's history of torpedopistols, so I think they were far from being close to operational (hardly on prototype-status). They picked up the development with the optical pistol "Mücke" pistol in the 1960's, but this went no way as well.
Re: Sea mines
Hi,
I found that:
Type "blue": LMB with regular polarity magnetic firing device.
Type "red": LMB with reversed polarity magnetic firing device.
Type "green": LMB with acoustic firing device; has stripping prevention Equipment (GE) and period delay mechanism (Z.K.).
But I don't know what fuses and devices are in "yellow" LMB-III, and why BM-1000 is not color-coded?
Brgd, Igor

Re: Sea mines
Is this a sea mine, or a fishing device ?
Thank you.
Thank you.

Re: Sea mines
Probably a french moored contact mine (Vickers-Brequet). Originally a british development of an Italian mine ("Elia").von thoma wrote:Is this a sea mine, or a fishing device ?
It was introduced during WW1, but further developed after the war - like the "B3" variant in 1924. I have no idea what version this is though, as older minesystems (from around 1900) were used both during and post WW2.
In theory it could have been a mine from a WW1 minefield drifted ashore, but it doesn't appear to have been submerged that long.
