I'm about to re-roll some 120 Gold200 to 620 because I know that you are right, they won't listen to me (anr anyone else, probably). i just need to step away from the keyboard.
Good luck convincing Kodak to invest in new additions to their 120 film finishing equipment lines - particularly if the relative usage of 620 vs. 120 cameras is considered!
I have, but never in a "box camera", but a Rollei TLR. When I was young I seem to have thought Plus-X to be better because it was packaged in 5-roll 5ProPacks. Certainly that made it more professional! My photography mentor once laughed at me and pointed that out that logical fallicy as he recommended Verichrome but I was too arrogant to listen. And then that day happened when the camera shop had no Plus-X but had Verichrome. Dumb luck opened my eyes a bit more than they were previously opened.

I was a convicted Plus-X user and once the shop was out of Plus-X so I reluctantly bought Verichrome. It was actually a better film for general photography.
You probably mean Plus-X. In fact, Plus-X was available in size 120 but for a short period of time in the 50s.It is a bit difficult to compare Verichrome Pan and Plus-X" sharpness" experiences from my memories, because Verichrome Pan was never available in 135 or 120 sizes,

I was talking about earlier incarnations of Plus-X. First, it was available only in 35 mm then for a few years in roll-film formats, then there was Plus-X Professional and Plus-X again. Its history deserves a separate thread.Nope - I used the current versions of Plus-X in 120 for many years
Meanwhile, I checked the development times for Verichrome Pan in Kodak Data Books of Applied Photography (1968 revision) and they are as on the sticker. The change was before 1968. If anyone has an earlier version of datasheet FM-49 (issues A and B) could you please check the development times in stock D76 and Microdol-X?
When I was quite a lot younger I figured that Verichrome Pan was not as good because... I could get it at the local drugstore - 620 roll film. I shot it in a used Voigtlander Brillant, a birthday present when I was about 12 years old, I think. My pop thought the fact that it had a Heliar lens was significant; to me, just another oldish camera. But... I did take a lot of pictures with it.I have, but never in a "box camera", but a Rollei TLR. When I was young I seem to have thought Plus-X to be better because it was packaged in 5-roll 5ProPacks.

Page 37 gives the development times : D-76 = 8 minutes, Microdol = 10 minutes.
Yes, I also noticed a big difference in the development times for 828 and all other formats.Oh wait... higher up on page 37 it gives times of 12 minutes, for "Roll Film and Film Pack." For both developers.

Verichrome Pan was discontinued because it contained Cadmium. To come up with a replacement would require R&D. Why would Kodak spend R&D money for a film with virtually no demand?
I think I found the answer:
"Verichrome Pan also first appeared in the UK in 1956. Initially at 80ASA, it went up to 125ASA when the speed 'Safety Factor' was removed in 1960."
You probably mean Plus-X. In fact, Plus-X was available in size 120 but for a short period of time in the 50s.
I am still interested in finding the answer to when the emulsion/development times were changed. I assume that the label in the photo would only be used for a couple of years before photographers became aware of the change.
Thank you for narrowing down the time frame for this change. I also suspect that the change was due to new standards. If the emulsions were changed Kodak would have probably introduced new brands of film.At first I was skeptical that the change between 1958 and 1966 is related to the 1961elimination of the ASA safety factor, since that changed film speed numbers.
Yes although the stuff I once developed had only lain in the camera with exposures taken for about 40- 45 yearsIt is interesting that VP/V has such good latent image retention - certainly confirmed with folks who process film found in old box cameras.
Many folks shot VP in their Rolleis, having discovered that, for them, it was the best film around.
