The end credits appear to have come off some badly transferred 16mm syndication prints while the audio clearly is off the same masters as the episode content. Sponsor logos would have been on any 35mm negs or prints. These transfers certainly weren't from the camera negatives. I'm just pleased that the episodes look so good. The credits are a distraction but I can live with it. What's more annoying us the terrible job they did with the bonus episodes of the Bob Cummings and Stu Erwin shows which look almost as bad as those end credits.
