Hahaha., Sorry for my ignorance. After watching your video and the difficult part of making the bits I was having no other option to know what exactly the match lock loading system is and I found out this.

The matchlock was the first mechanism invented to facilitate the firing of a hand-held firearm. .... historians noted that, along with slingshots, matchlock rifle weapons were used by the elderly for self-defense and by the militaries of the Ras.

Among the numerous music videos, photo related blogs this stands out different, so I enjoyed it, But one suggestion though that form next time you could add some lines along with the video to tell the readers what exactly is about it.

Thank you, Cheers
