If you are still searching, here is my two cents. If the stopper fits securely into the bottle and does not fall out if you lift upside down (over a soft-landing, mind you), then it is likely the right one. Cant tell from your photos if it "fits" the style, your bottle appears frosted mostly, the stopper appears to be clear. If it fits its overall appearance and ambiance of the bottle and the stopper fits as described above, you likely have a winner.
As to the maker of this bottle, looks like it was mold blown/manufacturer. Again better photos would help. I can recommend that you go to www.perfumebottles.org
and write to our Archivist. If this was a commercial bottle (ie held perfume at one time) then she will likely be able to help (again with better photos).
