understanding the rear sprocket

I just now disassembled the rear sprocket of my old
Crescent model.

On one of the parts, it says "Made in Germany".

Here are two photos:

I just thought of a pleasant and interesting game:
What are the names of the parts? What are their
properties and purposes? What tools/substances are
involved in repair and maintenance? And what is the
conventional wisdom of do and don't?

I am engrossed by Images...in Lancia pillar suspension there's a photo of a buck.

Standard German coaster brake (can't read brake arm). Komet,
Centrix, Durex, Torpedo all similar design and small parts
interchange.

You probably don't have the lockring wrench:

aside from that, normal tools. Set bearings to a slight
trace of play at the rim. More info he

Indeed, it says something on it, I now remember.
I'll get back to you on that.

I don't have that. I got the piece of advice in
another thread I should get a cone wrench for the
cones on the front wheel axle. What I understand
a cone wrench is an ordinary fixed-size wrench
(block key), only instead of perhaps 7 mm it is ~2 mm
so it can be fixed on a cone. Your tools look somewhat
like that, or are they yet another tool?

Anyway, I looked for a cone wrench at Clas Ohlson,
which is the prefered place for cheap-but-good Chinese
tools in Sweden. They had block keys of all sizes, but
all were too thick to serve as cone wrenches. I didn't
know of lockring wrenches until now, so I didn't ask.

It's probably easier to get a cone wrench from a bicycle tool seller -
Park Tools, for example. I've found them in conventional tool shops
but usually in a big box marked "One piece, One dollar" :-)

When I assembled the sprocket I read - indeed, on the
brake arm - "Torpedo", so you're absolutely right!

I didn't know exactly what to do but I put some fat on
the ball bearings as well as a very thin layer on
everything else, and put everything together as a kid
would with LEGO.

Assembled:
