Mystery Shotgun With a Very Unusual Action

Cool Forgotten Weapons merch! This is a commercial pump-action shotgun manufactured in France and proofed at the St Etienne proof house. I know basically nothing else of its provenance, including who designed it, who sold it (although I would assume Manufrance...) or when it was in production (assuming it did get into serial production). What I do know is that it has a quite unusual and very interesting operating mechanism, and I wanted to take my limited access with it to at least show you that! Thanks to Ader of Paris for the chance to film this very cool piece of firearms history. Contact: Forgotten Weapons 6281 N. Oracle 36270 Tucson, AZ 85740
