There were also some differences between Baroque and modern bows that affect playing technique.
There's also something called the curved bow which supposedly was in use in Bach's day. I have this.

It's been years since I listened to it, but I don't remember hearing any important differences from standard bows.
I culled this some years ago.
Firstly I didn't think his interpretation was that engaging.
Secondly he lets the long notes sound a bit longer than on can do with a standard bow, but since one already hears the notes in question in one's inner ear, his efforts add nothing of practical interest.
