Well, as requested, here is my Darth Vader hookah. Its all black, and looks amazing IMHO. I am not sure on the maker or anythign like that. It smokes really well, picked it up on ebay a while back for 100 after shipping and handling. I think originally it was a single hose with a purge valve, but the two hose setup is working very well.
