Thought I'd share this interesting (to me

) vase. Rightly or wrongly, I've always associated this type as being of Scandinavian origin and know several companies made them. However, I came across this one today with its original label "HAND BLOWN / Lefton's Japan / GLASS WORKS".
I've included a pic. of the base as well.
Does anyone know if this could be the same company shown here?
