I don't know about hand tanks for roll film, but I had lunch today with several fellow Kodak retirees and one of them brought a 4X5 Kodachrome image he had taken from about 1950. We all agreed it must have an experimental coating, since a corner was 'clipped' with no notch code. I'm sure it must have been processed by hand in sheet film tanks.
