Fougera sell Calomel ( mercury chloride) , but the third letter on the label don't seem to be a L
So you have a Box manufactured in France that originally contain tubing with a food and drug sticker under a French sticker and a French label ... I think they reuse the box and add the stickers, in that case it will remove the value of the original box to a collector of such item
it was imported into the united states and had to have the food and drug stamp put on first because they were the importer is the way I read it and it is a l the originals are all in the box so it was not reused nothing missing nothing added and the seal is still on the back .I was the one that opened the box for the first time to see what was inside. There is also the little metal thing to pop the top off the glass in the box. Each little bottle is labeled Calomel.
