I had a quick look at the online version for the Arwas book, but there aren't any viewable pages regarding this online for the book. (I'd love a copy of that book)
Truitt's says
'After several years of refusal, Moser was finally given permission to build his own glass manufacturing facility in Dvory, near Karlovy Vary. ...'
and
'With the opening of the glass house in Dvory (in 1893), the company was reorganized as a private stock company and named 'Karlsbader Glasindustrie Gesellschaft, Ludwig Moser und Sohne'.
