Identification assistance

[US-Subs]

I picked up some curious pieces recently, as I slowly get them sorted I will have many questions on identification. Here are a couple to begin - A German toolbox, Google can translate "Spare Parts and Tools", but I doubt that they are for "Explosive Grab B". A little help?
Second is the remains of a training board, German? And for what? There are the remains of several cut-off detonators along the bottom edge...
Then there is a US device, possibly CAD or pyro related, but believed to be aircraft related.
Finally (for now) are a couple of what appear to be mine fuzing or control units, Eastern Bloc. These could be fakes/copies/training clones as the font/paint/markings used are similar to that used by some commercial marketers.

In the past there were several topics on this forum about subject #1. Search for Sprenggreifer.

Designed mainly for use in anti-moored sea mine sweeps, intended to snag on and cut the mooring cable.

In this case, Spreng Greifer B more or less translates to 'Explosive Grapple' [type] 'B'.

The word in photo 148 means "inert" in Russian.

So, maybe it was equipment from the East German Navy.

It's designed entirely for cutting anchorwires of moored minesystems... The proper english term for "Sprenggreifer" is "Explosive cutter".
