They closed down the factory in Marsberg, Paulinenstraße, somewhere in the early 90´s. To that time
a friend of mine worked there as a printer.
Their factory in Essentho, 4km from Marsberg, used to produce their own machine-blown stemware.
I don´t think I´ve heard this production stopped... Some of their machine-blown decorative items are
well executed (possibly with some hand finish, don´t know). Some even so well they sometimes manage
to sneak into collections as Art Déco...
