Hello Simba,
As mentioned by Mosquito, this model was also used by Verlys, however, there is a slight difference.
You have several panels/partitions, whatever you'd like to call them, on the side and the VSL Luxval model 'Noemi' has 14 panels, the Verlys version has 16.
From what i can see, i can count 14 so i would say it is made by Val St Lambert. It also visible in the catalogue of 1913 as 'coupe à pied' (footed bowl) and was in 1934 re-introduced as 'Coupe Noemi' for the Luxval range, together with some other models.
Earlier pressed glass pieces we're not always signed (pre Luxval), the later pieces were not always signed either, because the signature on the mold had worn out, so it is difficult to date this piece from an image, but i hope this helps anyway.
