The PBD had its production facilities in the town of Hilversum.
The story of the PBD is an interesting one, when they started to use
the word Delft as part of the mark underneath the owners of the Porceleyne
fles factory tried to stop them from doing so. They started a
few court cases against the PBD but never managed to stop the PBD
from using the word Delft. This is probably why many other
factories, other then the Porceleyne fles started producing what
people now call "Delftware".
From 1903 - 1920 their pieces can be recognised by a triangle,
sometimes with the letters P.B.D inside, but more often like in the
P.W. left under the triangle are the initials of the Painter.
The Roman letters under the triangle indicate in which month it was made.
The "G: is the year mark.
According to the literature the "A" was used in 1903, a "B" in 1904 and so on until 1920, where they
used an "S". This does not match the items I have, I believe they started in 1902. Look HERE for a further explanation.
The "J" was never used, presumably to avoid confusion with the letter "I".
They stopped the production of pottery in 1921, but resumed again in 1923
this time through until 1946, but it seems this was on a much smaller
