Here is what someone had to say about it.
There are "deep groove" originals and "non-deep groove" originals. The deep groove ring on any LP simply means that it was made in a press that had a specific configuration to locking in the stamper plates. This method of securing the plates in the press resulted in the ring in the label area that came to be known as the "deep groove". In spite of what people seem to think, the ring has nothing to do with the grooves or the actual pressing whatsoever. The stampers that were used in the press contain all the markings in the dead wax (and the quality of the grooves that are pressed as well). The label "ring" does not change or reference this in any way.
Having worked with a small record company in the 1970s and early 80's I had all this explained to me at that time from an old time record producer who had supervised and approved the pressing of his LPs for (at that time) twenty or thirty years. My observation and research over the years since has confirmed what I was shown. I've had Lexington address Blue Notes, New York address Prestige LPs, Riversides and Savoys - all of them both with and without the ring and they otherwise have the same markings in the dead wax that so called "original deep groove" pressings have. I have also been unable to detect any difference in the audio quality.
