This is the two screw version of the Dalbey's in aqua.  My three screw version in clear is here.  This one has most of it's very rare original closure.  The only part that's missing is the plate held to the top of the jar.  The three screw version I have has three "pads" around the jar with leather stuffed behind each one.  This one has a "ring of leather around the entire jar.  I'm not sure whether this is a distinction of two screw Dalbey jars or whether there are three screw ones with a ring rather than a pad.  Given the scarcity of these jars and especially ones with completed closures, it's a bit difficult to say.

I wanted a Dalbey's for the longest time before I got my first one.  I remember it used to be on the cover of the RedBook and that's where I first fell in love with the crazy closure.
