Collect the clues before drawing a conclusion
- Copy the catalogue number and photograph both labels.
- Read the runout markings on both sides, preserving letters, spaces and symbols.
- Note the country, mono or stereo format, label design and sleeve details.
- Check inserts and printed dates, remembering that sleeves can be swapped.
Read the runout in context
Runout markings can identify a cut, engineer, pressing plant or other production detail. Their meaning varies by plant and period. They do not universally identify an exact stamper or prove a first pressing by themselves.
Compare the complete combination with well-documented copies of that release and country. A database entry with clear images and matching identifiers is more useful than a listing that simply says “original”. If two details disagree, keep looking rather than choosing the more valuable answer.
Save what you know, including the question marks
In samla.ai, add close-ups of the label and runout, then review the suggested identification. Keep the markings in your notes even after you have found a likely match. “Possibly the first UK pressing; label variant still to check” gives you a sensible place to resume.
Does A1 or B1 always mean a first pressing?
No. Matrix conventions differ. Compare the markings with documented copies of the particular release.
Can the sleeve establish the pressing?
It is one clue. Labels and runout markings are also important, and sleeves may have been exchanged.
