Sorry, I am not familiar with this bottle or the company in general. If you remove the base embossing from the picture, there is not much value there.
The question is - are collectors interested in this piece because of its attribution to that factory. This is definitely the case with many other nondescript bottles from other glass houses.
Found this further info on De Steiger and the company on Tod von Mechow's site:
