Steve, no not a "test pressing" as you figured out. But certainly one of the early pressings off of the master as this is the first group of discs available, before pressings available to dealers after April 13, 1983.
Note; that was at my very first CES. In total I attended 43 CES. Unfortunately, they were nearly always all work and little time to roam the show. Only those in Chicago (back then there were 2 CES per year, Las Vegas for Winter and Chicago for Summer) was I able to roam the show because very few of my dealers attended the Chicago show. CES soon became just one show per year, Winter show at Las Vegas. At the Las Vegas show I was swamped, typically with 2 business meetings simultaneously, bouncing between tables, from morning to end of day. It's nice to be retired now😊 I've been building my present system since leaving the workforce.
