It is listed as 2007 Deluxe Edition in my official records , not to be confused with the actual Second Edition . This webpage only focuses on UK versions but it provides an acceptable listing of various editions of The Silmarillion 42 <| sep |> Literally everyone in some way or another , but primarily parents and relatives , teachers , community leaders , government , and each individual themselves . <| sep |> Well like everyone else said , the SubTank Mini did go through a couple of silent revisions , so it might be that . I was however looking at the machining itself , or the fingerprint the machine is leaving . Notice the strokes on the drip tip , or the way the airflow is set up in the bottom . Looks like they were manufactured in different factories . Anyways I did get an authentic SubTank mini that was just subpar QC and is whistling on the middle airflow . Kanger slip quite often with their QC I think . Do mention the supplier when you narrow it down , it ' s certainly going to help .
