Kammermusicus und Violinist der Hofopern-Kapelle in Berlin (1762-1831). 2 letters, the first hand, in the U.S. "J Kolbe", the second probably dictates, with eifh. U. "Kolbe". 2 p. to 2 double bl. Kl. 8vo. Potsdam 1793 and 9.IV.1797. The first letter to a High Noble-born. "...oversend hiebey some avertissements. If there are prenumerants again, please tell me at the specified time.
