I know very little information about this glassmaker.
From Wikipedia: Kosta Glasbruk later known as Kosta Boda, is a Swedish glassworks founded by two foreign officers in Charles XII's army, Anders Koskull and Georg Bogislaus Staël von Holstein, in 1742. The name is a portmanteau of the founders' surnames, Ko(skull) + Sta(el). It is located in Kosta, Sweden, which was named for the company. The surrounding region has become known as the "Kingdom of Crystal" and is now a tourist site which attracts a million visitors annually.
The drawing from the 1940 catalog represents the DROTT HX pattern.
