Well, there it is! A pair of real Asian cannons, at last! The top one is especially curious, as it appears it was maybe wielded like a pistol-gripped shotgun!

After seeing this post over the weekend and thus widening my search for other nationalities, I did manage to stumble across a Chinese example that is similar to what I'm looking for, with the buttstock included. Granted, this has a longer barrel, but the technology is essentially the same, and I don't think it is a stretch to consider that guns like mine might have had similar stocks.
