Hallmarks have been used in Norway
since the Sixteenth Century. The system included,
at various times and in various combinations; city
marks, assayer's marks, date letters, date numbers,
and maker's marks. The farther a piece was made
from the main population centers of Oslo (Christiana),
Bergen and Trondheim, the more likely there were
to be mark inconsistencies. The bureaucracy in control
of silver marking seesawed between the Crown and
the Silver Guilds for a few centuries and finally,
in 1891, a simplified national system was established
that is still in use.
The current system requires only
a silver standard mark and maker's mark. The old
Norwegian standard of .830 purity silver is still
used, but beginning around 1920, .925 purity began
replacing it and is now the foremost standard in
use. Town names are sometimes included with the
required marks and the letters "NM" (Norsk
Mønster) are sometimes seen on flatware,
they are an indication of patent or copyright.
Below are illustrations of many of the latter 19th
and 20th century silver producers of Norway. I will
add to it as I find or am sent mark illustrations.

DAVID-ANDERSEN
The company was founded in Christiania (now Oslo),
Norway by David Andersen in 1876. Andersen (1843-1901)
was a gold and silversmith with a keen sense of
quality and the high standards of his workmanship
brought early success. By 1888, Andersen was able
to expand his workshop into a steam powered plant
and a second retail location was opened in Oslo
in 1892. David Andersen died in 1901 and his son,
Arthur Andersen, took the reins of the firm. Arthur
instituted some important changes, he decided to
hyphenate the family name to David-Andersen, and
as chief designer, he introduced the use of enameling
on the company's gold and silver jewelry and holloware.
The new line was so successful that enamelled jewelry
has become nearly synonymous with the David-Andersen
name. The firm has always remained a family business
and is now run by members of the fourth generation,
Uni and Jon David-Andersen.
The company has kept pace with changing times and
artistic trends, they have produced beautiful and
finely crafted jewelry and objects in the styles
of; Naturalism, Dragestil (Dragonstyle), Art Nouveau,
Art Deco, Art Moderne, and Modernism. A few of their
early designers include:
Arthur David-Andersen (1875•1970)
Johan Lund (active 1890's)
Gustav Guadernack (1865•1914)
Guttorm Gagnes (1906•1964)
Ivar David-Andersen (1903•1998)
