What are these?

[Motiztab]

First I have two of these, one very flat and this.
I was dismissing this from having a military connection untill obtaining a second today even if its flat. Both came out of the sea, understood from old firing range's.

Also from the same area is this cone shaped item, its about the same size as a 20mm shell case its made of brass but so far i have not found any markings.

If your looking for a image with some reference points both items can be seen in my first post of today.

Fuze covers.

As Hicky says pictures 1 to 4 are Fuze protectors for Fuzes like Number 390 and the like all of which are secured by a shaped band over the largest diameter of the fuze.

The last item could be a copper jacketed Projectile for something like a 50 cal BMG or possibly the "Slug" from a fired HEAT round although the shape is too uniform-
What size is it ?
Is it magnetic ??

Is it solid ?
What material is it made of?
:hmmmm2:
