Default joytech rear hub

Today I came across an interesting rear hub.
It is a single speed mechanism but unlike the
familiar Torpedo hub the brake cylinder is made
out of two loose parts. To mount the thing
first a cylinder screw is put into the hub
shell, then the brake parts are dropped down,
last a cone is put down the axle to hook both
into two pins, *and* into the brake parts that
are positioned at opposite side.

The hub doesn't have a name on any part what
I can see save for the brake arm which has the
word "joytech" on it.

Anyone has any information or images from this
kind of hub?
