BD Dukoff Hollywood (1949):
These brass mouthpieces were produced in two halves that were silver soldered together (much like the Otto Link.) They had a large chamber and rounded inner side walls. Only about 200 of these mouthpieces were made. And, about 100 of these blanks were sold to Zimberoff, who produced a mouthpiece under their own name. The white bite-plates continued with these models. This same mouthpiece was also sold under the name Zimberoff - House of Note. Some of these had the model name Vibra Metal. (Theo Wanne)
