yep and because the Indian govt. kept devaluing the Gulf Rupee the Arab states got rid of it in 1966 except for Oman (1970). I believe Qatar actually closed all their borders in June 1966 while calling in all the Rupees and temporarily used the Saudi riyal for a few months while the Qatar Dubai riyal was printed and they (Qatar/Dubai) lasted until 1973.
