Here is a copy of the article from my set of Antique Phonograph Monthly’s that Rod Pickett is referring to “The Beginning of “Dubbed" Edison Blue Amberol Cylinders”. Great information.

Now, from what I have read in the Blue Amberol books, I thought the dubbing process was acoustic, rather than pantographic: they even display diagrams of the dubbing setup. Operating a pantograph, where the reproducing and recording styli are moving at different speeds (150 vs. <200 tpi), seems to me a formidable engineering challenge.

Were talking 1900 in this thread on brown wax cylinders. It was about 1915 the acoustical, horn dubbing from Diamond Disc to four minute master cylinder started. The pant-o-graph process was for brown wax cylinders. It looks like by the mid 1890's By the round recordings were sold as some of the cylinders, however some masters were used to make duplicates by the Gold Moulding process to make a number of sub masters that were used on the pant-o-graph duplicators. It was not like the hot wax process used to make commercial "Gold Moulded" records, but rather, the Gold Molding process was used to create molds, however a close fitting brown wax blank was put in the mold, and a mandrel inserted as the mold was heated, and the blank expanded (also a mandrel forced the blank to the sound grooves.) when this cooled the brown wax blank had the grooves of the mold in the cylinder, that a number of these were used on the duplication machines to copy commercial brown wax for customers. :!:
