The instructions for seasoning Cast Iron pans, evolved throughout the years. I find the progression interesting. Even the manufacturers modernized their methods, with advances in their own products/ technology. The old original product labels illustrate that. Even better, are the advertisements from each time period. Old Catalogs give information also.
We have many of the above archived throughout our members only sections, so if this is your area of interest, certainly you should consider joining WAGS, which will certainly provide you with access to some of the above. :) :)
Myself... well I think that modern methods of seasoning are superior, so I'll stick with those! :) :) The advent and advances in vegetable oils, etc., not to mention the joy of newfangled stoves which give us options and choices that our grandmothers and great-grandmothers never could have dreamed of! (nor the Manufacturers for that matter!)
