That is an excellent question.
A few years ago I was assisting a friend with identifing a Persian pen box. Everything I had found in hard copy except for short articles in English and other languages on the subject was in Farsi. Eventually found a scholar at the V&A who had co-written a monograph on the subject with Dr Nasser D. Khalili who was able to assist.
The Khalili collection which made up of eight different massive collections, one of which includes Islamic Arts. See http://www.khalili.org/
Dr Nasser is himself Iranian. Their contact e-mail is firstname.lastname@example.org
I'm sure Dr Nasser himself will not be responding but hopefully you will hear back from them.
Please post anything you may find out here so that we might all benefit.
