Here's a little hilarity that was posted on the French forum, linked to a French auction site (leboncoin). It's being offered by someone in Pontarlier, titled "Magnificent Absinthe Brouilleur.
Superb absinthe brouilleur of cover design. With perfectly symmetrical dome to divide the water and make it run all the way along the drain, pierced with 26 round holdes, rigorously identical. ... Made of aluminum, a very rare metal at the end of the 19th century, this brouilleur is not referenced in any of the books on absithe rituals. This is indeed a moving testiment of an era of new inventions, like the see-saw broullleur, which is much more common. It is most likely an ultra-rare prototype, which is astonishing given the ease of use and the efficiency of the system. Indeed, in use, it reveals itself as exceptionally efficient for preparing an absinthe. Alas, it is not hallmarked, which confirms the hypothesis of a prototype. In addition, one can balance the sugar on the point of the cone: this could have been used as a game of chance for whoever managed to balance it. The winner would pay for the next round. Make a serious offer.
