An infrequent forum visitor but I've owned a number of SOTA's over the years, Series I-III and still have two Oakland Star III's. SOTA put out a newsletter dated September 1989 which indicates that you have a Series III version. They were made between January 1987 and September 1988. I hope that answers your first question.
I have an SME V on one of my decks and it's mounted on their Cosmos armboard. As part of the setup just make sure that the platter is level and that you have the right amount of weight (lead shot) in the well under the armboard so that the sub chassis is properly balance within the plinth.
