It's small concealable gun that can be fit in a palm. I have heard it called a "lemon squeezer". It's a hammerless .32 caliber squeeze gun.
It is similar to, if not the gun, that Leon Czolgosz used to assassinate William McKinley in 1901.

I think this type of pistol was used in the assasination of president Garfield or McKinley, I'm not sure which one.

Beat me to it also, it is a gun.

It is a 32 caliber pistol. Manufactured by the Chicago Fire Arms Co. The model name is "Protector", patented in 1883.

I believe it is known as a Chicago Protector palm pistol.

According to another website, Leon Czolgosz used a .32 Iver Johnson hammerless revolver to shoot and kill McKinley, not a pistol such as this.

It's an authentic Victorian compactable pizza cutterwheel. Used in olden Italy during the early 1800s.

Gun

It is a "turret pistol." It holds seven cartridges. This gun is cocked by squeezing in the lever sticking out on the right, and is fired by pressing a small trigger lever just under the barrel. What appears to be an abrasive wheel in the center is a knurled inset that the user rests their thumb against to steady the gun when cocking and firing.

You would place the gun in the palm of the right hand, with the curved lever against the heel of the hand. Then wrap your fingers around it with the barrel protruding between the index and middle finger.

This style of gun is commonly known as a turret revolver.

It's a safe combination chamber.

It is the French Turbiaux Palm Squeezer Pistol patented by Jaques E. Turbiaux in the year 1882.

I was gonna guess a stove, but everyone seems to be certain that it's a gun.

I figured that the round part was the burner, and the tube on the left goes out to a butane tank.

This is a russian made hand cruppler. A Weevolint inspector uses this small device to make a nonsymetrical hole from which to draw a sample for semi-destructive testing. The device had to be small so that it could be concealed from the Weevolint, else drastic violence may ensue. Weevolints were finally made extinct during the Bavarian Ice riots of 1932.

I would love to owne one but they cost to much for me!

Lee Van Cleef used one of these in the film Return of Sabata and it is definitely a pistol. They were originally conceived in France as a weapon for assassins and was originally available in a 10 shot 6mm and 7 shot 7mm. In the US it was chambered for .22,.32 center fire and .32 rimfire cartridges. A really nice one would probably go for $2500-$3000 today.
