Re: what is this?
A better picture is necessary. Both if you want proper identification beyond the fact that is indeed a Syrian style hookah but also so you can know what you are actually buying. Is the stem etched? Is it smooth? Is is scuffed up or tarnished? I can't see enough to answer any of these questions. Hell, it could have a crack in the you can't even see.
Best of luck in any decision you make though.
