The mark is for Kosta, this vase predates the merger with Boda. According to Ivo's book (Miller's Glass Fact File a-z) LH is for Lindstrand Handmade, numbers in the range 1640-1784 date between 1958-61. I'm not sure if the year is the design year or production year. Either way it's a very desireable vase and a great find at £3.50 :mrgreen:
