Such are what gun collectors long for.
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!
