OP, I can give you some examples what the numbers etched into the dead wax mean. Each record label has their own system.
Here’s an early 1st pressing of a Kate Bush album, the matrix number is:
The catalogue number and county of origin is included;
89 is side A, 90 is side B. The -1 means it’s the first production run on stamper #1.
The question is was this vinyl pressed early in the run when the stamper was new, or was it pressed late when the stamper was becoming worn and needed to be changed?
The only way I know of is to play it. There may be additional etched numbers which identify it. And the mastering engineer and record plant code may be scratched into the runout. A -2 may also be on a first pressing.
These are pressed later with a different stamper but may be of better SQ because they were at the beginning of the production run.
As stated earlier, the label is important in identifying early and late pressings. Record companies change the label for various reasons, eg, which country it’s released, reissue, early issue.
Steve Hoffman forum has lots of info on first issues and best quality pressings.
