R.L. Burnside: See My Jumper Hanging On the Line (1978)

Grégory asks:

What guitar is that? Looks like a Teisco or Kawai from the late 60s early 70s... The video is from 1978. What's that piece of metal doing on the top of the fretboard? That's not just a fret zero... 

Any ideas? Personally, I'm more inclined towards it being a Kawai; I don't think it's a Teisco.
