I read the response which is what I expected. Donor playfields, backglasses and plastics can sometimes be proto or have differences. Back in the day, WMS may have used 2-3 different companies to produce their playfields. NOS playfield could have even been a reject or a test run. Only an observant collector will find the differences in some cases. In this case, I would have no hesitation in using the current artwork in any of my games as it is 100% better than anything else out there. But well done on highlighting this to CPR so that future runs will be consistent with the original run of playfields.
