Now that looking at the OM back Ted posted (Ted, thx for posting that) and realized that upside down 649 factory overprint was printed about the same place as the place of the OM back. If the printer made mistakes of feeding uncut sheets upside down and printed those 649 factory overprints, they would have been printed on the higher portion of the back, right? And what's the chance of feeding SC and OM sheets upside down and made the same mistake. That's wacky!
