In the Kosta catalogues from 1926, 1933, 1940 and 1944 we can find a guilloché service called Lina.
In one of our two pattern books (coming from Kosta) there is a rubbing of a glass.
The pattern s simple but elegant, and has probably been made at several glassworks.
We have unverified information that Skruf also made a service called Lina, which was similar to Kosta's Lina.
The museum has several glasses with this, or similar, pattern - some probably are Lina from Kosta: slightly pear-shaped cup, stem with knop.
The guilloché pattern has a double zigzag border at the top, two straight lines below that, and four lines in the festoons.
Based on the above, we think we have four Lina from Kosta.
In the picture below we have four glasses with four lines in the festoons.
