I've been ordering a number of documents from the UK (TNA) and US (NARA) national archives lately, sharing cost for copies with others (including several AHF-members).

I'm pausing the orderering now, but I have a few documents I'd still like to get copies of, concerning german minesweeping. It's a document in five volumes, titled "Technical and operational history of German minesweeping", of which I have already bought volume 1.

I'd like to see if there's an interest for these documents by others in here, so we can make an joint order sharing the costs for the remaining 4 volumes (the package will also include some other documents on the topic which I have aquired). I will need another 6-7 persons to make the order affordable.

Please send a mail or PM for more information!

I took this photo of sea mine in Museo Storico Navale in Venice. Any thoughts about what model is it?

I can't help with any specific info, but it's obviously a mine intended for being laid from a submarine.

Can't see the photo. It says there are 15 photos or so but typically facebook unfriendliness don't let me see them.

Hello to all :D; a little more........................

German Sea mines.

The Group of five German air mines (LM), which were dropped from the aircraft with a parachute over sea and land, consisted of large seaworthy bombs of types of LMA, LMB, LMC, LMD and LMF. There was not an LME."

The model LMB could be converted for launching from a ship LMB (S) - S for Schiff

Hello to all, new to the forum, looking for information on German SMA mines and the Shafts mechanism used to launch them, have small amount of information gather from the net, but the drawing of the shafts (from Type VIID and Type XB) only show one shaft with the release mechanism and the bevel gears for the two? vertical shafts. Also looking for drawing of the SMA sinker used in the shafts? I believe that the SMA was deployed, both as a contact mine with horns and as a magnetic mine, but have not seen any drawing that show the different layout?

SMA was an influence mine (magnetic), not contact.

Thanks Natter, did you find a source of a full copy of O.P. No. 1673A - German Underwater Ordnance, Mines? I think the index has the SMA on page 77?

That's correct.
Unfortunately, my copy is of rather poor quality. Here is an image of the complete system:
