Qajar painting technique

In order to undertake a conservation treatment on a large Qajar
painting on canvas (supposedly oil, beginning 19th century), I am
trying to find information on the materials and painting technique
of the Qajar painters: old recipes they might have used, technical
studies on their materials and technique, any hint on the media and
the varnishes they used, the way they painted, or any indication of
where I should look, who I should contact. I thank you in advance,
