I did some googling for the phrases "presse manchots" and "penguin press", combined with "Kerguelen". I couldn't find any reference, anywhere, to this device being a penguin press- though of course the phrase "penguin press" is difficult to google because of the publishing house.

I did find another, very different, device in this French news article which is a peat press in a Paris museum exhibit about Kerguelen, which was mistakenly called a "penguin press". It was actually used to make peat bricks, either as building material or as fuel.

So is there some myth that means that any press-like device on Kerguelen is assumed to have been used on penguins?
