Made by Pukeberg Glassbruk Sweden 1915-1930, but attributed variously to Pukeberg, Steven & Williams, and McKee (not). Replacements lists this as Pukeberg. According to Sid Lethbridge in 2006, "The Pukeberg, Sweden glass factory is still in operation and have confirmed that they made this pattern. It was likely designed by Harald Notini."
The names "turkey tracks" and "royal fan" have been applied to this pattern by collectors, but the manufacturer's name was Solfjader, which translated is Fan.
The stemware has also been found in amber/vaseline.
There is an American patent for this pattern to J. H. Venon in 1927. Venon was an importer; it is likely that he obtained the patent to protect his product.
