A Friend found this beautiful image in an old book on World Music.Starting from left:
1st guy is holding an Esraj. Looks like there are no sympathetics. And there seem to be sound holes on the top section of the sound-box as well. very interesting ...
2nd guy's instrument looks to be a Sitar.
3rd guy's looks like a Veena - although I am not certain.
4th guy is holding a Taus. Doesnt look like the ones you see nowadays - but very cool nonetheless.
