Can anyone identify these?

[Bob Walker]

Anyone know what these bits are alongside what I assume is a Mauser bullet?

Hey Bob ,

 

The brass ring I'am pretty sure is part of a fuse cap and the iron disc is a pusher plate from a shrapnel shell ( to push the shrapnel balls out of the head ) . BTW the Mauser case looks like it has the remains of its head , so prob still live .  DD

Top one is a ring from a (probably) No80 fuze for British 18pdr shrapnel shells. The groove in the bottom contained a powder train which burnt at a set rate. By rotating these rings the burning time could be changed and the fuze set to function at a set time(=distance). The steel plate is indeed the push plate or diaphragm from the same type of shell, this sat at the base of the shell and the hole in the middle was for a brass pipe which communicated the flash burn from the fuze down to a cup full of black powder, this detonated and pressed the plate up the inside of the shell body, ejecting the shrapnel balls & fuze.
