This is a really interesting video for several reasons.
- It outlines the progression of firearm development in the world, which isn't what you probably thought.
- Many famous firearm pioneers worked for this guy
- It shows a firearm that is over 200 years old but appears still functional.
- It also shows an example of a barrel that was patched.
- It has a very unique lock system

Interesting.

Puckle's Gun, 1719. Used interchangeable casings. Called the "first machine gun."

That's cool, really interesting to see things like this video on the subject...

Thanks...interesting and looks like he looks at development of other firearms.
