Old manual purported to be from KFC settles 4 major issues

I think on a low side 2.5Lbs to 3Lbs of seasoning and equal salt would be close to a starting number

So let's look at the ingredient weights for the seasoning packets I can find photos of.

Seasoned Flour as referenced in the manual:

Flour - No kidding
Salt - Total sum of all salt =>30g in our recipes
MSG
White Pepper
Black Pepper
Vegetable Herbs and Spices

So from this the total amount of Herbs and Spices and Garlic has to be less than the weight of Black Pepper. Figure where most folks set Black Pepper to. (2.5g plus or minus) Part of why I'm considering a higher pepper amount.

Now let's assume that for this manual it's a 2.5lb(40oz) seasoning bag they reference. And let's assume that the ingredient weight didn't change much and can still be validated against the seasoned flour.

40oz bag:

Herbs and Spices (includes pepper)
MSG - So rules out some sky high value here. I talk about I+G later.
Additional Salt
Garlic Powder

So a couple things.

I speculated that MSG was 1lb at this time in a 2.5lb seasoning bag. So that scales to 8g in our recipes. Where does that leave the boundaries for the weights of the other ingredients? I do have a chart with some ball park numbers. There isn't a ton of real combinations.

Also, I now stand even firmer on there just wasn't as much H&S as I had originally thought back when.

One last item.

The 26oz seasoning bag.

MSG
Herbs and Spices (includes pepper)
Additional Salt
Garlic Powder

I am considering now that perhaps only 2 items significantly changed. MSG was lowered but made up for in I+G. And Pepper was lowered in favor of an extract. If other Herbs or Spices were replaced by an extract it would be minimal

Sorry - Long post and probably should have been placed in the radical idea thread. Once I have more calculations done. If it's becomes a worthy discussion I will move the recipe build phase to the radical recipe thread.

Also - Let's stick to the time frame of this manual to current for discussion. Not what he built in his home style kitchen in 1939.

I also think additional salt was reduced in the 26oz seasoning

A very good post overall, but I don't think you can validly make the presumption that the sum total weight for all "other" H&S must 'collectively' sum to less than the weight of Black Pepper.  I believe the legal interpretation here is more likely to be that no single "other" H&S ingredient when isolated can weigh more than Black Pepper.
