Now let's see...
I have some pictures from the showroom, and I might have been wrong...
There are more than three kits! The Mahogany kit I never got a picture on! The maple one is stain in ebony, and there is another maple kit on tube, and perhaps another one beside it!
Anyway, from what John Good said the shells were made by a conga maker in Thailand, who supposedly is the best around. The shells are stave, and the scoped out, as he put it.
Well, I don't know, but they sound huge, and they sound GOOD!
I just lend the kit to a friend with a great drum studio, so maybe I can get some sound clips along the way.
Some more pics from the DW showroom, all stave kits:
