Can anyone identify the maker of this perfume bottle? It is marked on the base FRANCE, with 539 below that. I have tried to get a good picture of the base, but it is extremely difficult. There isn't enough contrast. I am wondering if the number refers to a Choisy-le-roi catalogue number. The bottle measures about 19 cm tall and 10 cm at the widest point. The opalescent glass is quite thin, as you can see from the main picture. The design is Art Deco, but that doesn't necessarily mean it dates from 1930 or thereabout.
Any pointers are appreciated. Thanks in advance.
