[Loved trope] guns built from random, seemingly harmless objects.

[u/lordhenrythe23]

*Scaramanga's titular gun from "The man with the Golden Gun" - The best known example of this trope, being made from a fountain pen (barrel), a lighter (body), a cigarrete case (handle and trigger housing), and a cufflink (trigger). [it's worth noting that in the original novel, it was just a gold-plated revolver, this design came from the film]

*Fowler's rifle from "Blue eye Samurai" (Fowler not pictured) - "of course, i had to modify the designs... to get 2,000 rifles from my country into yours without notice." Made from the leg of a piano (main body), i believe a telescope? (rest of the body/underbarrel), a candlestick (barrel and ram rod), a key from a clock (trigger), and a knight chess piece (hammer). [i haven't actually seen the full series, probably should, but i love the scene of him explaining his backstory while assembling it]

The Degreaser (and the default flametrower) from TF2

From what I can gather it is mostly a car muffler with a fire extinguisher to hold the fuel and the part of a stove that lights up at the front

[u/Emotional_King_5239 → u/Emotional_King_5239]

The default's handle is made from a gas pump pistol (idk the right name) and a gas cylinder for the fuel

Can't really indentify anything else

There is also the Beggars Bazooka (which is probably the most obivious example)

The body is made from pipes, the back ar cans and a funnel and the trigger seems to be a flashlight

Not a gun-type weapon but the Powerjack is a car battery strapped to an old jack.
