This is the ultimately rare 1st generation Illadelph Coil Condenser. These were blown by Luca himself (the founder of Illadelph and the inventor of the freezer coil), mine was made in early 2005. 7mm thick walls, 9mm thick coil, beaker bottom, 5 slit hand blown diffuser. Of course I have the active carbon filter and ice pinch bowl on it.
This thing is one big piece. A few years later illadelph started the 2 piece coil and then every chinese company came in and tried to knock it off.
