Hello, Orchidians! I am Mariano from Vicenza - North Italy. I am
searching for a xeroxed copy of the old booklet by H. De Koningh
"The preparation of Precious and other Metalwork for Enamelling"
published in 1929 as I can’t find out here in Italy. Is there anyone
that can help me? Thank You very much For Your precious help !
