Ian McCollum of forgottenweapons.com has a great video showing disassembly of this firearm [0]. His youtube channel [1] is also a great resource if you like seeing the insides of all the crazy firearm designs there are (and were), with a good dose of geopolitics and history thrown in.<p>[0] - <a href="https://www.youtube.com/watch?v=g_3AoDf7CeE" rel="nofollow">https://www.youtube.com/watch?v=g_3AoDf7CeE</a>

This video shows how the Owen Gun works: <a href="https://www.youtube.com/watch?v=_5kW4sKd-sQ" rel="nofollow">https://www.youtube.com/watch?v=_5kW4sKd-sQ</a><p>I think the Owen Gun is not just interesting because it was a successful indigenous Australian design, but also because it was so clearly designed for reliability. The Sten Gun in comparison was designed to be extremely cheap to manufacture and did not have a reputation for reliability.
Wow, look at the stark simplicity of that gun. As an engineer/programmer, there's something appealing about simple, durable machines like that.
