Rindskopf Art Nouveau purple oil spot iridescent glass vase

This was a must have, "bucket list" piece that I was thrilled to win on eBay UK, even if I did have to stay awake to an unholy hour in order to make my last second bid!
In 1995, I purchased a vase in this same shape but with a very different decor - it was a pale green opaline with a decal portrait of a child surrounded by hand painted foliage. I ended up selling it around 2015, & a few years later I discovered it again on CW, in Ales' (larksel) collection, among various other examples in the same distinctive shape, identified as Rindskopf.
Well, from then on I wanted to get any decor in this shape to make up for my error.
Finally, I found this fine example in the oil spot/papillion type decor on a purple ground.
It measures 12 cm tall, 6 cm across the cut & polished top rim, & 5 cm across the base.
Made by Rindskopf, circa 1900.
