Chuck Wagner is one of the more interesting collectors on Turkotek. He recently posted this bag on Turkotek (http://www.turkotek.com/VB37/showthread.php?t=1382&page=2) and called it Baluch citing the Koneiczny book.
Chuck may well be right but I noticed a little something about the tassels. If the bag is Baluch the tassels by implication are also Baluch work. They are extremely similar to the tassels on this Mashwanni Bridal Mafrash
There are people called Mashwanni who weave the black Afghan rugs and bags. perhaps they are Baluch. I have never clear about exactly who those people are. But Mashwanni were written about in the Baburnama which dates to the very early 16th century.
