Can you provide a scale of the item?

Looks to be a water proof case [?] so I would have a guess that it may have some naval or marine aplication .Sounds silly but is it a primer for a larger shell or powder charge ,as in naval guns?

Possibly a flare?

I think gunman is correct. After some browsing the net, it appears to be a percussion (of course) lock primer (as opposed to a case primer). Lock primers had extractor grooves, later case primers often were screwed into the case via two spanner holes.

My guess is this is a WW1 era design. There were British guns that were labeled as QF type (quick firing) that used a similar primer.

Thanks fellas, appreciate all the input.

I may be, and probably am a mile off here, but could it be launching shell for a ball or maybe anti zeppelin chain shot ?
I've read that the British navy were issued with the latter which may have needed to have been waterproof
Probably wrong but just a thought
Quick edit... I've just found a picture of the anti zeppelin shells but they are a full length brass cased shell. Not like the ones you have sorry.

It could be a shell for a line throwing gun ?

Just a WAG, but maybe it's used for launching a line from ship to ship?

I think a line thrower shells are likely to be much larger. Today, a line thrower is a rocket propelled device. The one my friend has is about 1 3/4" diameter x about 7-8" long.
