Just found your site. Seems very helpful.
Today I unpacked a Kjellander Vase, it was last packed up in 1979 (per the newspaper in which it was wrapped).
It is a clear, crystal vase, footed and 6" tall. On one side is a knight, slaying a dragon; on the other side is a damsel, praying for rescue.
the base is 3" by 4" and the top edge of the vase is 5/8" beveled and smoothly polished.
The signature is just Kjellander with the numbers: 376-282
I'd attach photos but, I am not sure they are the right size.
