Early 37mm Identification

[US-Subs]

Been asked to assist on the identification on this early 37mm. The owner knows nothing about ordnance, grandfather was in France in WWI. While the projectile looks fairly generic, I don't think I've seen anything with a shoulder this sharp on the case. Gordon? BTW, I asked for better photos, these are them -

Most likely a lighter in the form of a shell.

The case looks like it could be lathe turned rather than drawn.

I am thinking it may be a display piece made to look like a cartridge as it also has no driving band.

I wonder if the "projectile" unscrews or otherwise separates. There may be a cigarette lighter or similar underneath it.

EDIT: It looks like I was typing this reply at the same time as Burney Davis.

This person, as in the person who asked USSUBS, posted the same item on a ordnance group on facebook and was given nearly the same responses I am already seeing here. Guess he didn't like our evaluations.

The "case" looks like turned from a solid bar of copper.

Thanks to all.

I've no idea - but if there was to be a 37mm rimfire this is it ! - some kind of mock up, does the top unscrew ?

All I got was the pictures, no further information.
