Anyone have information on a Stolva Wien military bag?

I picked up this camouflage army bag when i was a kid but never knew much about it. I still can't figure out where it's from or what it was for. It has a bunch of metal clips and buckles that hang on it. There are words on the underside flap that says "Stolva Wien". From what I can tell, that's a company that made or makes leather goods. Also on it are the words Ges-Gesch which apparently means "protected by law" or "copyrighted" in german. Anyone have any ideas where I should look as to what this bag was used for or how old it may be? If anyone has intimate military knowledge, I can upload a picture of it and include the link here. I'm really curious about its history.
