The article lacks IMO the most gruesome tool that was used for processing penguins, the penguin press : https://ssz.fr/brdl/presse-manchots.jpg I took it on Kerguelen island, that's not a very good picture but you get the idea, a nice engineering detail is that the handle that turns the spiked rollers also has a blade and slices the pressed penguins into smaller slices. Most of the time though (at least on Kerguelen)…
If they have any oral history or anything of the sort...
