It may be some bizarre Frankenweapon a mad gunsmith came up with.

If not, the basic design and weirdness of it looks like the kind of stuff they were doing in the 1870-1920 period. The hinge-open, top-break design was also common in that time period. The frame style looks like those used by Hopkins & Allen in that time period as well, making me think even more that it's a Frankenweapon.
