Popin A Belfort?

I found this yesterday at a flea market. The stamp says Popin A Belfort and it came in a wooden case. The wooden case has leather (so old and hard) on both sides and the case looks like a strop. The scales look like someone made them as a replacement which makes me think someone might have made the case as well. Does anyone know anything about the stamp Popin A Belfort?

I apologize for the bad photos. I'm using my cell.

I also found this one and just had to get it.

Nice scores. Know nothing about the Popin A Belfort but I love the W&B

Thanks! The W&B was in great shape so I couldn't pass it up. I did see a Henkels 7 day set with black scales but I wasn't willing to part with the amount of money they were asking for.
