submarine mine mechanism ?

[ytarg]

Hi,

These 3 mechanism are just coming from the son of a man who worked in submarine mines in France just after WWII. It was told me that they are probably part of these submarine mines.
The markings are german but the waffenamt code are for me unknow ...
Do you know what is it ?
Thanks.

They certainly look German. Perhaps there is a Kriegsmarine M item code in the same way there are Luftwaffe L and Ln inventory codes for equipment. I have no idea really, but perhaps they could be depth charges time and depth fuses. Just a kind guess.
