Which books do you have please? and which would you recommend as the most comprehensive for the period 1800-1850/60?
"Graflich Schaffgotsch'sche Josephinenhutte 1842-1900", "Barock und Rokoko im Hirschberger Tal", "Fritz Heckert 1866-1923".
For paperweights, the book by Marek Kordasiewicz.
My area of interest is the Isergebirge, which means Karlsthal, Hoffnungsthal, Josephinenhutte, and Neuwelt/Novy Svet.
