I never noticed this before, because I always assumed that it was a PS85. How very interesting!
Now that I've seen the video (too bad there aren't any close-up stills from that tournament available online, where we can have a clear view of that racquet), I am wondering if what he was wielding was a forerunner of the Reflex/Odyssey series. The smaller open throat, the slightly more rounded head, the softer feel - these are all features that distinguished the latter from the PS series. Plus, the PS 85 frame geometry was largely based on that of the Sting Mid (minus the stabilizer bar and slightly beefed up), which was already available in '83, so why would they make such a big change to the frame less than a year before the commercial release, only to change it back months later?
Is it possible that Wilson was developing a number of new frames in parallel, from the stiffer model that was on track to become the PS to a softer version that later became the Odyssey, and Connors happened to prefer the softy at that time, which was then painted to look like the PS for him to use in these tournaments? Does the racquet on the left resemble the ones you had strung?
My Odyssey Comp was made in 1988, likely by Long-Yi (rather than San Ho Sun). It may be one of the last Wilson models made without a bumper; something that was quickly becoming an anachronism by then. Perhaps Wilson was recycling their R&D materials from the early '80s, and decided to commercialize the prototype that Connors once preferred over the PS85? It may have been marketed as a cheapo racquet, but it is a buttery smooth frame; one of my all time favorites.
Incidentally, watching Chris Evert returning Roscoe Tanner's serves with her wooden racquet was the true highlight of the video for me.
