I bought 12 bagfaces some 7 years ago.
Here are 5 of them.

An Armenian friend collected them in the sixties in central Iran. I always thought them to be Bachtiar. The striped back kilims are all cut off and sold separately.

Some have cotton warps, some have cotton and wool and goathair warps, some have wool warps.
All cotton and wool is 2 ply.

The knots are all symmetrical.

Best regards,

Vincent

Without any first hand knowledge, I have always been told and assumed that these were Bakhtiari as well.
