:hi: The Swedish website you link to does not attribute your orange vase, and I find the Riihimäen Lasi sticker quite convincing. I would not think that each and every vase made at Riihimäki is properly documented or known, so don't let that spoil your fun. Also you might consider, why would anyone go through the trouble of changing a sticker from one vase onto another, and then put it on a fleamarket?
