@Momentrabbit Yeah, that definitely doesn't look like wear. Any idea what the country of origin might be?
@Momentrabbit Hm. I'm always curious to learn where a part's steel originates. It's such an ancient technology and yet to this day, the material quality varies wildly from country to country.
@mawr Haven't the faintest. I'd expect there are knockoffs all over the place, tho, and I know 'resourceful' our parts scroungers can get... so I'm actually vaguely pleased to see the inside isn't pot metal or depleted uranium.
