I came across these videos of kendo taken around the year 1897 on the YouTube site Olden Days. Both have been restored and colorized for maximize viewing quality. This is one of those times when you don't even have to be a practitioner of the sword arts, you can just be a fan of history to get a lot out of them!
The first appears to be an Ona-ha Itto-Ryu demonstration.
The second is a clip of students during a kendo practice.
Enjoy!
