-----Original Message----- From phillip holmes: "...if the deadwax info is the same on a supposed test pressing as a WLP or first issue, it probably isn't a test pressing? ..." I've never encountered the term deadwax before. A test pressing would be identical to the first issue (assuming the press run had been approved!) except for what was typically a reversed scrap label which sometimes had ID information written on it. (I've occasionally seen a plant use a special test pressing label but usually not.) When they start a pressing run the first few will often be bad because the press temperature hasn't stabilized. For this reason they might press ten, throw out the first three because of non-fill, check one out with a microscope, play it, put a couple on file and send the remaining four or five to the client. If a client was smart, they'd file away at least one to prove what they'd signed off on had been ok in the event of a bad pressing run. The rest would be passed on for the producer and engineers to check. I would be very surprised to see test pressings that weren't actually promo copies turning up very often among collectors.
