Strangest gun designs

I say that the physics are pretty limiting when it comes to geometry, such that any gun is basically forced to at least look like a gun: it needs a barrel, handle, and trigger and there are only so many reasonable ways for those three things to go together.
Slamfire shotgun made out of a piece of pipe doesn't have a trigger or a handle. Just a piece of pipe. Two pipes where one fits inside the other loose enough to slide and that holds a shell in place. Larger pipe has a little something protruding from the inside at just the right spot so when you slam the one down inside the other, the protrusion hits the firing pin and sets off the powder charge. Looks like a pipe. Deadly.
 
I'm having a small debate with a friend of mine:

He insists that there have to be some really strange gun geometries out there, something that's barely recognizable as a gun but still fires.

I say that the physics are pretty limiting when it comes to geometry, such that any gun is basically forced to at least look like a gun: it needs a barrel, handle, and trigger and there are only so many reasonable ways for those three things to go together.

Regardless, what are the strangest looking guns you're aware of? What are the weirdest and funkiest designs out there? Let's see 'em!

So don't read the thread if it doesn't interest you?
No, see the thread DOES interest me if it were to stay on course.

I could easily post photos of my several Mateba Unicas, Semmerlings, Sommer & Ockenfuss rifles, COP-4s, JoLoArs, a duck foot, belt-fed Robinson Armament M96, an August Schuler Brevet pistol, AK based shotguns, Harpoon guns, Knife guns, Liberators, Martini match rifle, Calicos, among others, etc. but they still all look like guns.

So my interest would be the same as what the O/P was expressing, hoping to see some really obscure designs that are not readily apparent as firearms like those I cited above. Maybe there's something out there I've never heard of or seen, something so obscure it's one of only a few made and it sits in a cagunner's personal collection.

Can you think of or have any such creatures to share?

The title of the thread is literally called "Strangest gun designs" with a picture of an MP5 trigger housing as the first post. I don't think OP had any intention of keeping the topic ONLY directed towards guns that don't actually look like guns, and was simply describing a conversation he had with a friend. If you want to participate, right on. If not, that's ok too, but if we only post guns that don't look like guns, the thread will be over almost as soon as it starts.

Fair enough. Let me see what I can dig up. I can post several from my own collection that certainly get some side-eye and scowls.

By all means. I get a kick out of seeing and learning about weird and wacky firearms.
 
Here's a few weirdos that I already had photos of - I really need to take more photos of other stuff when I get the chance.

  • August Schuler 4-barrled Brevet Pistol
  • BTJ .38-Special Derringer.
  • JoLoAr pistol in 9mm-Largo with palanca intact.
  • Several Matbea Unicas alongisde a Webley Fosbery. (Semi-automatic revolvers).
  • Semmerling LM4

I'm curious what the hammer/firing pin assembly on that August Schuler looks like.
 
German belt buckle gun - castle gun.
Apparently not 🥨 or German, but likely a post war oddity.
You would raise your hands in defeat, but a string up your sleeve opened the buckle presenting 2-4 spring loaded barrels that would automatically fire.
