US M2/M2A1 Flamethrower
Forgotten Weapons

After a dismal first attempt at designing a flamethrower (the M1) in 1941, the US Chemical Corps along with several universities and industrial partners put in a lot of research to develop a more usable and effective flamethrower. The result was the M2, which went into production in early 1944. It would prove to be an exceptionally effective weapon in the island-hopping campaign towards the end of the war.
The M2 was arguably the best flamethrower fielded by any military during the war, with a number of excellent design features. These included:
* A constant-pressure regulator to ensure that the range stayed the same from the first to the last shot of a tank of fuel
* An on/off main valve easily accessible to the operator
* A supremely waterproof and reliable pyrotechnic cartridge ignition system
* An auto-shutoff valve which sealed at the nozzle, preventing dribble (and cutting off fuel flow should the operator lose control of the weapon)
The M2 would see service into the Vietnam War even as its successor the M9 was being issued. It was a truly outstanding design, and remains viable to this day.
Thanks to Charlie Hobson for showing us the unit and teaching me to fire it, and also thanks to Adaptive Firearms for letting us use their range facilities!

Japanese Type 100 Flamethrower
The Japanese Type 93 and its slightly-improved sister the Type 100 were the standard flame weapons of the Imperial Japanese Army for its fighting in China and the Pacific. They are a smaller and handier design than the American weapons, and less user-friendly. The Type 100 uses a rotating valve t...

Bonus Content: Flamethrower safety dr...
Figured I'd post this since we got it all on video anyway - this is my final safety briefing/walkthrough with an M2 Flamethrower made in 1944, followed by my first short firings of it.
The gun was only partially filled with fuel, which is why the firing duration is so short.

Lewis Gas Operated Prototype Pistol
Isaac Newton Lewis is best known as the designer of the Lewis light machine gun, of course - but that was not his only work in the firearms field. In 1919, he patented a semiauto handgun using the same gas-operated, rotating bolt mechanism as the machine gun. It is a pretty massive steel beast of...
