Pallme Konig Kralik Iridescent Art Nouveu Vase

I recently purchased this beautiful vase at an estate auction. The auction had many high quality items and this vase is no other. I am looking for any information as to date, maker and other information on this piece. I checked it many times for imperfections; there are none. I had earlier correspondence and was told it is PK Pallme Konig Glass with red vein on green glass. I appreciate your time and expertise.
