Hi Rottenfuhre
Its a German seamine horn for the GZ mine which was 32 inches in diameter , had 5 lead hertz horns (that,s what they are called ) on the top half with 3 switches on the lower half. I cannot identify the brass fittings , at first thought they maybe the internals of the mine case , but will continue to reseach it for you

Hey there,
just reading your post.The parts are from a german EMA mine series WWI.
EMA stands for Einheits mine type "A".You have one horn with a copper center what is typical for these mines.The other device is the arming switch.The electric leads coming from the horn where wired to the contacts you see on your picture.Inside there is a contact plate under spring pressure.Normaly on the underside of the arming device ther is pin with a hole in it.When the mine whas dropped the minecase separeted from the mine anker.The minecase raised to the surface.During this moment a safety pin whas pulled out of the pin in the arming device.The spring pusched the contact plate closing the electric circuit and so arming the mine.Sorry for my Englisch.Whould it be possibel to have some pictures of the other underside of the arming device?

Thats a good result Paul ! i know the German EMA was used in WW2 as they had large stocks left over .the horn is the same as mine which came from a box marked GZ mine , thats why i thought it was that mine , but of course the Germans used these horns on several mines . very interesting thread.
Attached are pages from the Original German Naval manual showing that mine

What a great resource bocn is!!! These pieces are new to me and can be readily identified from the above information.
All these pieces came from the same mine, it unfortunately got cut up and scrapped around thirty years ago because it was in such a sorry state. However, a bit of foresight by the person cutting it meant that these few pieces were saved.
I have seen this mine reffered to as the type 'A' mine, c/12 mine and type II mine - which is the correct designation for it?
The main piece is the same as that shown above; an arming switch from the side of the mine. In addition to the arming switch itself, the fitment from the mine, the locking ring and part of the mine itself (with a few markings) are also present.
The second piece is a fitting for a hertz horn, cut out as one piece with part of the mine remaining. Having found a few pictures on the internet I believe this is the top fitting from the mine. These mines had five horns, four spaced equally around the upper hemisphere, and one on top. The fittings to the side have one edge lager than the other in order to compensate slightly for the curve, this one appears to be even all round, hence my thoughts that it is from the uppermost fitting.
The final piece is another fitment, this time I believe from the base of the mine. This one has been cleaned, to rid all parts of the mine casing but is exactly the same dimensions as that of the 'side fitting'. The reason I suspect that this is from the base and not the other piece, is that the IWM has a similar mine in their collection, when viewing the photo close up you can clearly see similar markings to those that appear on the fitting that I have put with the arming switch; now it is of course possible that the mine was marked on the base too, but given the location markings in this position would be difficult to read - (well thats my theory and I have been known to be wrong in the past- so if anyone knows for certain please let me know)
Now although after a lot of searching I have found a few photos of this WW1 mine on the internet, as yet I have not been able to find a drawing or indeed any information about the internal fitments on this mine. Does anyone have such a drawing of the internal arrangement? (or even better photos??)
Also, if anyone has a spare German WW1 hertz horn that would have fitted into this mine, I would love to hear from them, it would be great to display one in the fitting I have.
here are some pics

I finally managed to find a drawing of the mine showing internal layout, it clearly shows the parts I have, unfortunately much of the writing is too small to make out. Maybe someone has a better drawing of this mine which I believe is a German type E (the British gave it designation type II)
