Roy, I have not seen that bottle before, but the first thought that came into my mind was that if it showed up on the world's largest internet auction site, I would definitely consider bidding on it!
I have never had the misfortune of having a stuck perfume stopper, but the thought was always in the back of my mind that if I ever did, the first thing I would try was some kind of penetrating petroleum product like WD-40 to see if it might break up whatever was sticking it together.
