Rahat’s Harmonium

The letter of the day comes from Kuldeep Singh (posted with permission):

I read your interview with Rahat Fateh Ali Khan. It was extremely interesting to get to know some inside stuff of Rahat and his great Ustad Nusrat and his father, Farrukh.

I myself am learning how to play the harmonium but there is one favour I ask from you – can you find out which harmonium is used by Rahat.

This may sound very odd but I am in the process of looking for a harmonium to buy so I thought why not buy the same one used by the professionals.

Unfortunately, I have no way of answering Kuldeep’s question. If any of you know, please tell me and I’ll pass your answer on to Kuldeep.
