Hi - you are looking at a very interesting fretless acoustic guitar from India!
Sold by Bina Musical Instruments and branded 'Givson'.
This is a cool way to get an Indian sound on a recording without having a sitar or a sarod, etc.
I had this professionally setup with flatwound strings. It feels and sounds great and is so much fun to play - I'm really sad to see it go!
The grommets around the tuning pegs have been slowly disintegrating for years and don't affect anything, but I felt it was worth mentioning.
