Thanks to everyone that helped me to understand the process that is used to isolate the source of such a problem. It started with me noticing smudges when copying negatives and thinking there was an issue with the lab. Luckily, I quickly realized that the same smudges extended beyond one negative and some were in the same location.
I have now carefully cleaned the rear elements of the offending lenses and all spots are gone. So, again, thanks for taking your time to respond to this thread.
Thanks for sharing your journey in finding the culprit. Most people are too embarrassed to share their foibles, but I have found this thread most informative and appreciate you taking one for the team
