Other than the pics and the grind lock detail, there are no other 'marks or scars' that could lead to an identity. It's a bit larger than most other hand grinders, at about nine inches tall and six inches square, and grinds like crazy fast. It has a four-pointed conical burr, and the plaque that read 'Kaffee', but I've not seen another like it.
It resembles the cheap Chinese knock-offs that are primarily for looks, but it grinds remarkably well.
Anyone have any idea what beast this is?

Here's a shot of the grind lock detail:

I'd be happy to provide other angles, details, etc., if you have an idea that needs panning out.
