Amou Daria by Revillon" launched in 1935. Said to be named after a Central Asian (in Tibet) river, probably an area where the company acquired their furs. Tornade was said to be the re-branded fragrance 'Amou-Daria' according to Perfume Intelligence, however, I cannot see this as being true as both perfumes were being sold at the same time as evidenced by 1930s-1950s period newspaper ads.
