“Maison Fabricienne Industrielle et Commercielle Aron Biber” located in Warsaw. Besides phonograph records, the company also manufactured several models of “patented” gramophones “Zarya” that were sold for 20 to 60 rubles. (See. Aron Biber Trade Catalog)
Following is the extract from the Catalog regarding phonograph records:
“The Biber Company offers phonograph records in a special catalog, they are in big variety, on several languages, and of a very high quality while at very low prices. (The catalog is free, just include stamps on 14 kopecks for shipping)”
Aron Biber also sold “patented” gramophone needles looking very similar to needles of August Burchard. For more information look at “Fox auf 78 - Birgit Lotz Verlag - songster.de” presentation.
