I might get me one of these... It's both large and small enough, and the weathering potential is great indeed.
As far as I've gathered – das Werk is Modellbau Koenigs "own brand", and since Andys and MBK are in cooperation, I guess Andy got a test shot directly from the supplier.
Ushi, who's close to MBK as well, has one, using it for developing a laser cut dock to place it in. Apparenly there are figures in development as well.
As for the brand, well it did get my attention the first time I saw it. Not too sure about the aestestetics either though...
