Very good collection. I would like to add that Grant had to rely on Hill and others due to the fact that there were few publications allowed and those formulas were specifically selected for publication. The work published, in 1965, came from work that was current in about 1945.
In that work you put up, you will see a very early version of the coating block and coating blade that i used in training and later re-created for my current work on emulsions. The last variety at EK had vacuum hold down, hot and cold tempering capability and were used to coat strips of film up to about 14" in sizes from 35mm to 120 to 4x5. You could even get 5x7s with skill. You could get 2 4x5s or 2 35mm x 12" strips from each sheet of film.
