Let me start with A and come back to B later.
A is a form designed by Sven Palmqvist in 1960. The form is crystal,
and copper wheel engraved in a technique the Swedes call in English
The H on the form is quite new to me. I have looked for an engraver using this monogram and can find none.
One automatically thinks of Hald but I have never seen Orrefors work
signed this way.
One possibility is that some one bought the form and then engraved it.
There were several engraving shops in Sweden. The Kjellander family
did quality work throughout the 20th century.
Hope this helps. Bill Geary
