Clausophon

Clausophon, 1925 - 1929, holder Clemens Claus AG Thalheim / Erzgebirge (Germany), later Clausophon GmbH, Berlin. Later Kuechenmeister AG (Ultraphon).

Mostly own recordings, but also acquisitions of British Imperial matrices. Maybe there was a business connection to Imperial / crystal to England - striking is the similarity with the Oliver Records, who belonged to Imperial.
