The Kjellander styles and designs have been rehashed many times over by who ever was running the factory. With the caparative minamal wear to the base and the clarity on the glass used on your piece I'm sure the vase you have, has to be a sixties re-design, I recently bought another piece of Kjellander off eBay for the exorbitant price of £9. This piece is pre-1925, it shows in the forefront a young woman, standing on a rock at the edge of the sea shore handkerchief in hand waving off a three masted sailing ship, sailing away in the distance. This was a well documented design and was first used just prior to 1920. I do like your vase and if you decide to part with it keep me in mind. I collect mostly Scandinavian, but mainly items by Orrefors and by certain designers. But nothing after 1970. All the best to you. Den
