What period are these Insignia from?

Greetings,
I was offered these but I am not sure what period they are from.

I believe the first one to be Kasier time.

The chevrons are different than the WWII ones that I have handeled.

The Torpedo Patches are something that I do not encounter that often and am unsure of what timeframe they come from. many thanks in advance to all of those that take the time to reply!

To my humble knowledge they are all ww-2 related as far as i know

Why the torpedo-mechanics has a "unfinished" cog-wheel? Some "teeth" missing !

I was just thinking the same. Never seen one like this. Interesting, though.

For tat one I am not that sure, mostly because of the backing cloth type, others look nice, period ones and I would say 3rd Reich type.

This Matrosenstabsgefreiter wears the same type of hand-woven chevron in this pre-ww2 portrait.

All insignia from WW2, not Kaiserreich.
