Strange firearms thread

[Alan]

Okay, here's a Picture of the Day thread for strange firearms. Post pics of any unusual firearms you find. I'll start with this crazy old pistol that I think has some weird engineering. You can also add a note about its history or why it's interesting, let's see your weird finds

I saw this Napoleon’s three-chamber box lock pistol from the year 1802. It has an awesome history, but still looks strange to me
