Hi Bernie,
To expand a bit on what Bill was saying and what I have learned over the years, is that whilst the GS became the GS2 around 1981 the 1 group machines had minimal changes to the appearance when compared with 2, 3 and 4 group machines.
On 1 group machines they are essentially the same from the early 70's up to the end of the 80's. The frame and body panels are the same except for those that Bill listed - the metal end panels and steam knobs. Whilst it says GS on the badge it is really the 2nd series GS.
In later years you will see semi-auto machines (like Barry's that he had on Craiglist). Kent also told me that towards the end of the 80's the plastic panel with the Marzocco logo was dropped, and the steel extension on the cup warming tray was added. Curioiusly this machines has the logo plexi and the extension.
On another note I can tell you that my 1 group GS and yours are twins. Mine born just a few moments before yours....11681 !!! Is that great or what?
Paul
