Vintage Elis Eiler Berg Kosta Hexagon Vase #1215, 5-1/2" tall and 4.25" wide - authentic HEAVY

Elis Eiler Bergh Kosta Heavy Vase in Hexagon Shape 5-1/2” tall 4.25” wide and weighs 4.3 lbs. Base is etched Kosta B. #1215. There are some issues with the vase, the top has a chip “inside” the glass and one of the sides also has a scratch inside the glass. I have run my fingers authentic over it and there are no outside scratches. The base has surface scratches. Overall, it displays well. I have been educated by a kind, thoughtful gentleman that this vase is from the 1930's and is rare.
