Case in point: A NOS RCA reissue copy of a Broadway play originally recorded in 1964 and pressed in 1974, wafer thin and flexible, purchased from Georgia and delivered to Ohio during the deepest of February's deep-freezes, flat. Still had the original price sticker from whatever out-of-business retailer and has gone through who-knows-how-many hands.
A good example of the the golden age of record pressing. Records did not come from the plant warped as they do today. LPs weren't always perfect, but the quality control was tight and the Cutters and line workers were craftsmen.
It's true that today's record plants are backed up with heavy volume, but I also believe this is a new generation of worker who can't quickly spot a defect on the vinyl before it is shipped out.
