As an afterthought, you need couplers, solvents, about 9 emulsions, sensitzing dyes, a colloid mill, scavengers, acutance dyes, and a few more odds and ends, not to mention all of the formulas to prepare the above.
Reminds me of an old Melaine song "I have a pair of brand new roller skates, you have a brand new key". Of course the song was quite lurid in meaning, but the point applies. Having done every phase of Gold 400, I know all of the above. I also know the coating formula.
