I'm feeling the need for a round-up of what we've learned through the experiments and from what people have said they remember.
Flour: Definitely whole wheat. Possibility of other kinds of flour, but John tried a 'five whole grain flour,' and did not like the taste. Definitely no rice or soy flour. Not spelt flour, which was not commercially available until around 2006.
Eggs: Definitely; and definitely in greater amounts than in the typical cookie.
Sweetening: Some molasses, but probably not in syrup form; more likely some kind of less-refined sugar. Iris and Claire both remember that Ted Odell changed the sweetener during the time he baked the cookie. Iris remembers brown sugar in the original ingredients list, with honey added later. Claire clearly remembers when Odell substituted barley malt syrup for some other sweetener in the early 1980s.
Milk: Definitely. Could have been either liquid or powder. Whey has not yet been ruled in or out.
Oil: No good conclusions so far; could have been any kind of vegetable oil or butter. Maybe flax seed oil. Canola oil wasn't developed until 1978.
Leavening (baking soda or powder): No.
Spices: Nothing in any significant amount. Maybe a little cinnamon. Definitely not nutmeg.
Raisins: Donna is adamant that there were no raisins; but when chopped up, they seem so right to the rest of us, for both taste and moisture. I agree with Donna, though, at least on the visual: even chopped up, the raisins just look wrong to me.
Nuts: Definitely. Walnuts, ground or finely chopped. Not almonds or peanuts.
Sesame seeds: Almost certainly.
Sunflower seeds: Probably.
Wheat germ: Probably.
Cracked wheat or bulghur: Probably.
Flax seeds: Deb commented with her specific memory that there was flax seed something. Oil? Meal? Whole seeds?
Oatmeal: Probably, but could have been barley. Barley flakes look like oatmeal, and I like what they did to the taste.
Brewer's Yeast: Not enough to affect the taste; I doubt it.
Millet: The grains look so right, but are just too hard. No.
Figs: The seeds look right, but the flavor is wrong. No.
Soy: No. Not oil, flour, or granules.
Corn meal: Definitely not.
Peanut butter: Definitely not.
