Gail, your set was indeed made by Pukeberg Glass. Here is the info you need:
Pukeberg Glasbruk, Sweden 1910-1920, designed by Harald Notini. Information obtained from Ami Fransson from ZERO INTERIOR/PUKEBERG GLASBRUK (Documented in Glowing Report, July 2007, pg. 1, the official publication of VASELINE GLASS COLLECTORS, INC.)
It is also listed that way in my ERRATA LIST (items 869-871):

p.s. All the other pieces on this page are also PUKEBERG!
