There's no maker's name on it. It's all but empty. My hunch is that it's a gun maintenance tool.
I'll put it in the cabinet where I keep special lubricants.

I found an all-metal version.
It's beautifully made; the cap is an exquisite bit of machining.
I'll put it in the cabinet with the plastic one.
