A 1960's black bakelite telescopic ear trumpet in its original box. The trumpet extends from 25 to 37 cm, is in perfect condition and is marked "Rochhausen 616 Waldkirchen". The box reads "Rochhausen Hörgerate - Service. 9367 Waldkirchen (Erzgeb.) Bez. Karl-Marx-Stadt". (Karl-Marx-Stadt was the name of the city of Chemnitz from 1953 to 1990 during the soviet occupation in Germany. The 4 digit zipcode was introduced 1965 in the GDR so the trumpet must date after that. Thanks to Stephanie Lange for this dating info).
