Can't ID it, but as to your observation about the oriental design, if I may add an observantion: oriental influences were very present in European designs since the late Victorian eara, due to some Japanese exhibitions (they inspired Gilbert and Sullivan to the Mikado), and I know the Ballet Russe were still designing oriental type costumes between 1909 and 1929 in France (and influencing fashion and design again in that area). A bit of a long time stretch to be working with, I'm afraid, so not very helpful, but oriental design fits the period and might point to areas where these influences were stronger.
