I think the DR series were built in India.
Wiki again.
The type was also manufactured under license in China, for the Republic of China Air Force, as well as in British India, for the Royal Air Force (RAF) and Royal Indian Air Force (RIAF).
DR is too late for the French ones when they were taken on charge, it was Hurricane II and Typhoon time. The series beginning with DR seem to be a hotchpot of different odd types that did not have a long production run. It looks as if somebody signalled the Airbox from India and requested a couple of dozen numbers; and that's what they got.
